Yes edam I wish there was too.
Britain did control Palestine but we left in 1948 as fed up with all the squabbling, and that's when the Isrealis seized land and villages off Palestinians and millions fled to refugee camps where they're still living.
Arab nations for decades hoped thro wars to gain land and rights back, Isrealis always win as have US backing(crappy potted history history I know but important). They have now all lost hope of this ever happening now. Un resolution from 1949 demands Palestinians right to return to their lands, no one thinks this is ever going to happen now.
So if born in extreme poverty, in a refugee camp, stories of parnts fprced off land (still have pistures and keys), watch parents daily humilaited at checkpoints, no hope no prospects, houses demolished at will etc etc your a 17yr old angry young man, might you not become a terrorist?
Terrorism is wrong. whether by a nation state or individual groups. But sometimes you have to stand back and ask why/ this doesn't justify it, but maybe there is a reason and understanding it can help find the solution.
