You would do well to to read your history…
First of all, not everyone fighting Israel is an “Islamist.” The issue isnt so simple that you can smply label everyone involved an Islamist.
The people of the region have genuine grievances.
One thing that is clear in history however, is that super powers never stand the test of time. The Israelis can bark as loud as they like and bite as often as they want, but history tells us that eventually they to will sucumb to the weight of their own indiscretion. America wont be there forever, and the Arab wont be helpless for ever either.
Its the Israelis who should learn that the tide is against them. Ultimately they will fall one way or the other. How it wil happen and when I dont know. But nations like Israel, that live on the misery of others are destined to colapse.
This video is a great illustration of the fact. Take away all their guns and these Israelis will colapse like cowards. Then it will be they who commit cowardly acts of terror as their people return to exile.
