Leaders of NATO agreed to build a rapid-response team that can quickly assemble if an aggressor crosses an allied country's border—namely, Russia. “Should you even think of attacking one ally, you will be facing the whole alliance,” Secretary General Anders Fogh Rasmussen said Friday. The force will be based in Eastern Europe. British Prime Minister David Cameron offered 3,500 personnel to the team and suggested its headquarters be in Poland with equipment stockpiled in the most eastern member countries. Rasmussen also noted that NATO is prepared to help fight back militants in Iraq, but there has not been a request from the Iraqi government.
