I've been convinced of this for some time as well.
For a while I thought 1993 was when the war started, with WTCI, then the more I read and heard, it became obvious that we (that is Western Civilization) have been under attack since 1973 when the US ambassador (I think that's who it was--Buckley) was kidnapped and killed in Lebanon.
When was the first attack outside of the Middle East? Was it in Munich at the Olympics in 1972? Ever since then, the islamos have been reaching outside of their area to hit us.
The decade of the 90s saw stepped-up aggression, which went unanswered each time we were hit. (I don't need to remind anyone here about just who was negligent either.)
There is a reason for this -- the Persian Gulf War began in 1991. Islamic terrorism is nothing more than a cover for the real cuprit here.
Go back and read my earlier post on this thread. I am becoming more convinced by the day that Iraq has been retaliating against the U.S. over the last ten years using the only means it has at its disposal -- by waging a low-grade guerilla war on U.S. soil.
