When Hamas came to power in 2006 (following a fair election, as confirmed by the UN and US), they repeatedly sent peace feelers to the Israeli government. They were clearly looking for some sort of settlement. However, the Israeli government dismissed those peace feelers. Hamas and the Israeli government eventually entered into a ceasefire, but even that was broken by the Israeli government soon after it was initiated. If Israel agrees to a two-state solution, which they currently show no sign of doing, there is ample evidence that Hamas would also agree despite what may have included in their charter.

Rejecting the state of Israel is in the old Hamas charter, not the updated one. It's also worth mentioning that when Hamas came to power in 2006, they repeatedly sent peace feelers to the Israeli government, which dismissed them all and later broke a ceasefire with Hamas. If Israel had responded positively to those gestures, we wouldn't be in this horrible situation today.

There is no evidence to suggest that Hamas or any other Muslim group intends to carry out military operations in Europe. This claim is propaganda by Israel aimed at securing military and political support from the West.
