Yes, there's something you're forgetting, Israel is America's best ally, it's distinctly unpatriotic to be against Israel.
Israel and the US have been on the same side of UN resolutions over 90% of the time. Meanwhile, the UK comes in 2nd at only 60%, it's not even a hard comparison to see which nation agrees with the US's global policy more often.
Beyond that, Israel is the only democracy in that area of the world (besides for being the only US ally in that part of the world too). If the US ever needs to go there for any reason (such as to launch an attack against Iran if they get nuclear weapons, or to prevent such) then Israel will be the launching point for any such operation.
Many people are against the funds the US gives to Israel without understanding the full effect of those funds. Those funds (however much they are) have a very important clause, they must be spent purchasing military hardware from the US. So imagine how the US's economy would be doing if tens of thousands of workers were fired because Israel was no longer obligated (or had the money) to purchase the military goods from the US. This would be further exacerbated by Israel then buying the military goods from China or Russia, rivals of the US, if they could get a better price.
By the way, here are some other nations and their agreement rates with the US on UN resolutions.
Great Britain voted with America 60% of the time.
Australia voted with America 56% of the time.
France voted with America 54% of the time.
Canada voted with America 49% of the time.
Japan voted with America 42% of the time
Kuwait votes against the United States 86% of the time.
Qatar votes against the United States 88% of the time.
Morocco votes against the United States 89%% of the time.
United Arab Emirates votes against the U. S. 88%% of the time.
Jordan votes against the United States 88% of the time. (To whom America gives $192 million annually)
Tunisia votes against the United States 89% of the time.
Saudi Arabia votes against the United States 90% of the time.
Yemen votes against the United States 88% of the time.
Algeria votes against the United States 88% of the time.
Oman votes against the United States 88% of the time.
Sudan votes against the United States 86% of the time.
Pakistan votes against the United States 87% of the time.
Libya votes against the United States 89% of the time.
Egypt votes against the United States 86% of the time. (To whom America gives 2 billion annually)
Lebanon votes against the United States 90% of the time.
India votes against the United States 79% of the time.
Syria votes against the United States 85% of the time.
Mauritania votes against the United States 90% off the time.
---------based on this if nothing else, what nations do you think the US should side with?

Now to discuss the entire 'Palestinian' aspect of your question
To start off there's a fact here that people like to conveniently forget: ***There never was a nation of Palestine***.
Until 135 CE is was called "Israel", it was then the Romans renamed their province (which included modern day Israel) Palaestina. Later in history there was then a series of Crusades, each one naming it in turn, such as the Kingdom of Jerusalem, Levant, and many others - but *never* Palestine. It then fell under various Arab rule (not being renamed during this period) until 1517 when the Ottoman Empire took control of it a named that area the Province of Syria - which includes modern day Syria, Lebanon, Israel, Jordan, part of Turkey and part of Iraq. It wasn't until 1917 that it was called Palestine in any form, the British Mandate of Palestine, but not an independent country. In 1948, the UN as a whole declared the State of Israel in that area (not in its current form), but the Arabs rejected creating a nation (which would have been called the State of Palestine) because they wanted all or none, so they got none. Promptly after having been created, 6 of the surrounding Arab nations attacked, and the newly created nation won - and fought them back including the newly conquered land as part of itself. In 1967, the Arab nations attack again, and lost again, Israel conquering new land but *not* including it as Israel, that is occupied land - of Syria, Jordan, and Egypt, until they returned the part they took from Egypt sans the Gaza strip, so only that small part of Syria and that of Jordan (the West Bank) was still occupied by Israel. Later, when Jordan (1994) finally made a peace treaty with Israel, they gave over the West Bank as part of the treaty, that land is Israel's, similarly Egypt did the same thing (1978) when they made peace with Israel.
Clearly, that shows the land rightfully does belong to Israel, considering the nations around it (Egypt and Jordan) turned over territory to Israel, yet it is often called 'disputed territories' or 'Palestinian territories' in maps, despite no nation there currently disputing it or no nation of 'Palestine' ever existing. The only piece of land currently occupied by Israel is that of the Golan Heights, a section of Syria, which Israel openly states to be occupied.
So at what point to the people who now call themselves 'Palestinians' come in? They're a rather new creation for the pure sake of sounding good in propaganda with no real basis - as clearly shown above.
Also, here is a map of the Biritsh Mandate of Palestine, circa 1922:
http://en.wikipedia.org/wiki/Image:Briti...
Note the large area which became the nation known as Jordan....
I quote from the The Covenant of the League of Nations, article 22, (which is the one that refers to defining what a mandate is) which states, "Certain communities formerly belonging to the Turkish Empire have reached a stage of development where their existence as independent nations can be provisionally recognized subject to the rendering of administrative advice and assistance by a Mandatory until such time as they are able to stand alone." The key words are **provisionally recognized**, not recognized. Directly afterwards it states, "The wishes of these communities must be a principal consideration in the selection of the Mandatory." Which is precisely what Britain did, the Jewish population agreed to a state, and the Arab population said all or nothing. Since the Jews wanted anything, they got what they wanted, and the Arabs got nothing, just as they wanted.
So a provisional, i.e. probationary, lable of 31 years allows people to call themselves under that name, and their descendents (who were born after it ceased to exist), by that name for all time? Under that reasoning, couldn't people in the southern States of the US call themselves Confederates?
Also, for those saying that all of the Jewish migrations are recent (i.e. only after WW2), that's just false. Ignoring the Jewish population which never left and existed as a minority since ancient times, every time Jews have been exiled from a nation or had excessive persecution, large numbers moved to Israel. Such as expulsion of Jews from England (1290), France (1391), Austria (1421), Spain (1492), and Portugal (1497), not to mention everything from the last half of the millennia.
Additionally, the Arab nations asked the Arab inhabitant of what was to become Israel to leave their homes prior to attacking Israel in 1948. The reason for this is that they didn't want to be inhibited in their attack by having to avoid killing Arabs. The Arabs willingly left, even more willing because they were promised the land of the Jews once 'the Jews have been pushed into the sea'. However, since Israel won, those 'Palestinians' were then left homeless. The Arab nations refused to help them: Jordan and Egypt stuck them in refugee camps, then left them there to garner world sympathy. At the same time one million Jewish refugees were thrown out of the Arab states, and Israel absorbed them.
At present, Hamas controls Gaza: this recognized terrorist group has been bombarding southern Israel with deadly rockets for years. Hamas has an official charter, and it states that only the total destruction of Israel will be 'satisfactory'. Hamas states that Israel has 'no right' to exist. So for Israel, it is an impossible situation, how can you make peace with someone who denies your very right to exist?
So to sum it up, there's plenty of propaganda which is causing the people who call themselves 'Palestinians' to react as they do. They live in squalor and poverty, often illiterate, and have been raised on propaganda and don't know their true origin, so of course they believe they are right and that Jews stole land from them - that's all they know.
