That's not what I'm talking about. There are ideologues in Europe, Persia, and Africa who feel unthreatened by Israeli retaliation. Some of the more sinister among that group may be actively supplying bomb materials to the PA and/or its various affiliate groups...thinking that they are beyond Israel's reach because they are so far from Israel itself.
I hold that Sharon may decide to rock their world, and if such a retaliation is large enough, such ideologues may be less motivated to risk their own hides in the future...thus reducing the PA's easy access to such bomb materials from foreign lands.
May be so, however, militant Islam is stronger then ever these days.
