The attacks of September 11 2001 on the World Trade Center in New York and on the Pentagon in Washington meant a break in the history in each regard. Additionally, these simultaneously executed attacks expressed a new face of terrorism and helped it to get a new quality of its world-wide acting. But wherein lay the differences between the so-called new terrorism and the one before the mentioned, outstanding date in the middle of September 2001? Can also new quality criteria be anticipated regarding its financing from this "new" terrorism? Do risen incomes stand in correlation to effects?
