If Canada, a soverign nation, were to allow a terrorist group to set up camp in southern Ontario, and they used that base to launch rockets at Detroit what would be the response of the USA? If Canada refused or was unable to control them would the USA invade and if so would it be justified? Would they call bombing Detroit an act of war?
This is the basket case that is the middle east.
If your neighbours don't throw rocks at your house, perhaps you won't feel the need to to throw bricks at theirs!

I think this analogy is not very accurate. I think a more accurate analogy would be this: if someone is standing on your neck with a big old boot, you're going to do whatever you can to try to get it off, even if it means jabbing your fountain pen in his leg. The guy with the boot would be Israel and the guy under his foot would be the Palestinians.
