Not only supplying Israel is the direct reason why US soldiers are being targeting but also it bace the way to radicalized the new bin laden and the new ISIS. Who would target US individuals and interests every where.

No one talk why bin laden became anti-usa eventhough he studied in western university and from a wealthy family. It is the US foreign affairs in supporting Israel that resulted in 9/11 directly or indirectly.
