I don't think those are fair statements.
First of all there was a kingdom of Israel, at least two actually and kingdom of Judea, albeit it was independent for a short period relatively. And it has absolutely nothing to do with the bible, those are historical facts supported by many archaeological findings and recorded history of the romans, assyrians etc.
Secondly, the major reason for jewish immigration to Israel is 2000 years of anti-semitism,persecution,progroms and finally the holocaust. Just looking at the number of immigrants before and after proves this beyond a shadow of doubt. True there was a small zionist movement before but the holocaust was surely the catalizator and the legetimazing factor which without it success of the zionist movement is anything but certain.
we also didn't "now choose" Jerusalem out of spite. It was our capital since day one in 48.
All of this is not to say that Israel legitimacy stems from any of those facts,it doesn't. It's legitimacy comes from it being given by the rightful owner of the land and it's independence being recognized by the UN and more importantly then those, it exist and has a right to under international law.
