You still don't get it.
Germany and Japan were not under armed occupation or being colonised by the countries they invaded.
Using your logic the French resistance should be regarded as terrorists because they attacked the occupiers of their country.
No, it is you who doesn't get it.
The French resistance were obviously terrorists - against the regime that was in place.
The Arabs are in Gaza and the countries around there because they colonised them. The Arabs come from the Arabian peninsula but spread out, mainly bringing cruelty and slavery to the new areas they terrorised (see Africa).
Then it was colonised by the Europeans.
Now the Jews have a tiny little nation there, having themselves originated in the area and following the massive flow of them from other middle eastern and northern countries into it.
Land gets claimed by people. Shock!
Have you any objections to the existence of Jordan, Pakistan and Bangladesh? They are all new countries that invovled mass movements of people and some chaos, and are arguably a form of "colonising".
No, you are specifically obsessed with Israel. I wonder why...
