Justify what?

Fighting to take their land back from illegal foreign invasion?

Why are you ok with the illegal seizure of land that as far as anyone can tell, literally just happened since the IDF was still there?

A bunch of foreign soldiers show up and point guns at you so if you don’t die right then it’s their forever?

I’m not trying to justify anything. I’m trying (and failing) to understand what you’re going on about.

If the original land owners had brought their own military with guns, would that mean they got it back, is that the difference?

So anyone with a gun just automatically gains land rights?
