BRUSSELS, Belgium (CNN) -- NATO, for the first time ever, has invoked the part of its charter that allows retaliation for any attack against one of its members. The organization invoked Article Five in support of the United States one day after terrorists destroyed New York's World Trade Center and damaged the Pentagon. The decision opens the way for NATO military and logistic support to any U.S. retaliation. In Washington, Secretary of State Colin Powell said the statement would allow a possible collective response once the U.S. has identified who was responsible for the attacks.
