President Barack Obama says today's main terrorist threat comes from decentralized al-Qaida affiliates and extremists.
Obama tells U.S. Military Academy graduates that this means the U.S. must work with countries where terrorist networks seek a foothold. He says working with allies will expand America's reach without the use of U.S. forces.
Obama says the threat from a decentralized al-Qaida lessens the possibility of large-scale 9/11-style attacks against the U.S.
But he says there is a heightened danger to U.S. personnel overseas.
