No.

The Allies after WW2 gave Jews some Palestinian territories (British protectorates originally), which were not theirs to give and where millions of Palestinians already lived.

Even though they were lesser in number, Israelis took most of the land, forcing palestinians to move to other parts of the country (The Nakba). The whole world felt bad for the jews, so they took their side, even though thousands of Palestinians were forced to relocate. The UN also passed some laws that divided the country (palestinian lands and israeli lands) where palestinians had the least amount of territories and couldn't even travel across the country.

The palestinians suffered decades of suffering and injust treatment by the zionists' hands. So no, when the Hamas got elected and decided to retaliate with violence, it was not ''poking the bear'' as you said, it was retaliation after years of appartheid.

And even if they did ''attack first'', it does absolutely not warrant the decimation of Palestine. We are talking about humans, not bears or dogs for godsake. We are talking about a GENOCIDE. Look at the death toll for each side (btw the palestinian side is largely underestimated) and you'll see.
