U.S. military strategy is changing. From Associated Press:
"After a decade of costly conflict in Iraq and Afghanistan, the American way of war is evolving toward less brawn, more guile.
Drone aircraft spy on and attack terrorists with no pilot in harm's way. Small teams of special operations troops quietly train and advise foreign forces. Viruses sent from computers to foreign networks strike silently, with no American fingerprint. It's war in the shadows, with the U.S. public largely in the dark."
In Pakistan, Yemen, Somalia, and Iran:
"The high-tech warfare allows Obama to target what the administration sees as the greatest threats to U.S. security, without the cost and liabilities of sending a swarm of ground troops to capture territory; some of them almost certainly would come home maimed or dead.But it also raises questions about accountability and the implications for international norms regarding the use of force outside of traditional armed conflict."
