Netanyahu is isolating his country as best he can - and he is risking the total destruction of his country, too.
This serves prophecy.
Netanyahu isn’t really trying to isolate his country. His aggressive land grabbing is causing other countries to cut ties with Israel. That would be a different prophecy and blows up your neat formula.
On a more geopolitic/geostrategic/psychological level, the Zionists (the secular and the religious alike) repeat an old strategy: the sacrifice (disappearence of "all European Jews" in the so called holocaust gave them the state of Israel "for they had to suffer so much". If the current war goes over the top, they will claim the sacrifice/disappearence of "all the Jews in Israel" - and will be rewarded with hosting the world government afterwards, in Jerusalem
Doesn’t work when Israel was the largest aggressor in the war. Israel was created to give the Jews their own homeland. That logic doesn’t work for a world government. Putting it in contested holy land would be one of the worst places to put it.
