That’s probably because Israel is a part of the Western world and nobody in their right mind is concerned about it becoming a military threat or sponsoring radical Islamists.
And yet the heavy hitters (Al Qaeda, ISIS and co) never really bothered with Israel. They went directly after other Western nations which supported the Palestinian cause and sponsored Palestinians with billions of dollars.
The concern isn't becoming radical Islamists but becoming no different. The behavior is the ultimate problem. I mean the Shakers are technically a radical Christian sect who doesn't believe in sexual reproduction. Radical Martha Stewart fans deciding to kill people would be just as big of a problem.
