Oh dear - you've had some poor answers to your important question.
The US, UK and Israel for a long time argued that the PLO party were the problem and prevented meaningful talks between Israel/Palestine.
It was the US who in 2002/3 put pressure on Palestine to have elections for a Prime Minister.
So Palestine agreed to hold elections. Hamas were told by US that they had to accept the outcome of the election. Initially Hamas were reluctant to take part, but they did eventually put up candidates. The elections were monitored independantly by US observers who reported the elections were one of the fairest and well organised they had ever witnessed.
Hamas won by a landslide. There is absolutely no doubt whatsoever they were the choice of the people. There is absolutely no doubt these were fair and properly conducted elections.
Countries like Japan and Sweden praised the election process and congratulated Hamas on winning so decisively.
US and US have been unable to bring themselves to accept the Hamas victory. They have run out of excuses. Palestine has done the the very thing US and UK used for a long time as the reason for the ongoing problem.
Former US President Jimmy Carter visited soon after and summarised the problem - that peace talks had stagnated,
"The problem is that Israel and the United States refuse to meet with someone who must be involved"
US and UK have no excuse. The people have chosen their leaders through fair democratic elections and those leaders should be recognised.
Since those elections nearly 3 years ago, Israel has imposed a blockade on Gaza - and the humanitarian crisis it has caused is coming to a head now with 1,500,000people trapped with little food or medical supplies getting through. (Israel has also frozen Palestines tax revenues)
And just to reply to the misinformed comments by some answers posted, Hamas also indicated that it was willing to recognise Israel’s existence and offered a ten year truce (I'll repeat that A TEN YEAR TRUCE) if Israel moved back to pre-1967 borders. Israel responded by starting a series military incursions - which of course triggered some return mortar fire into Israel.
Anyway - to answer your question: I don't know.
