'Their land'? Why any more so than third-generation Israelis living there now? Whatever it was sixty years ago, it's not theirs now.
So you do admit it got "conquered"?
And basing on that, validate their resistance?
Several Arab nations.
Which war you're talking about?
Like giving control of Gaza back to Palestinian groups? And by Israeli actions, you mean like trying to stop the ceaseless rocket attacks on their civilians without slaughtering innocents?
No. No.
Hell yeah it is. Guess maybe they shouldn't have kept on launching wars on Israel, or they would have more land then they do today.
Define "resistance".. "launch war" ?
