This was certainly true for the Irish Republican Army. Tom Clancy's book "Patriot Games" dealt with the scenario when a thug from an IRA splinter group broke the taboo.
I had not heard of a similar taboo with the jihadists. Don't you think 9/11 might have put a damper on fundraising here?
“Don’t you think 9/11 might have put a damper on fundraising here? “
No, I think its probably increased funding from muslims in the US. Not to mention the money our govt is giving them directly. aka $900 million to Hezbollah (or was it Hamas).
No. Between feeding their own machine (through contributions to 'humanitarian agencies'), and the liberals, progressives, and other ill/misinformed and stupid people out there, I have my doubts that they have suffered any great decline in fundraising. I also question where billions of dollars unaccounted for have gone during this administration.
