@AndreascondemnsIsrael First off, I think you're conflating cause and effect. If Israel didn't have to worry about "gruesome methods" - such as
suicide bus bombings, knife attacks, shootings, etc. - then there wouldn't be the same level of blockades and restrictions on movement. (And such attacks have happened since
long before the State was established.) I note that before this war, thousands of civilians from Gaza did have permission to cross the border to work or receive medical care; it's an international border - and has been since Israel pulled out in 2005 and renounced any claim to the territory - and it is treated as an international border, with the vetting and blockades that go along with that.
