U.S. under attack by every single country

Late at night, the sirens will go off in every city. People will rush to their t.v.'s to hear Obama's national address. "United States of America....is under attack."
Gasp, we will!
The American people will stare at each other in disbelief, checking outside for bullet sounds and loud chants from foreign soldiers.
Our allies have betrayed us, our U.S. controlled countries have rebelled, and we are left with nothing but unprepared people, weapons, and nuclear weapons.
"Stay calm," the president reassure,"It is just a mild...." The televisions shut off, the citiy lights went off, the electricity was shut off. The sirens were all that stood.
The east cost and the west cost were the most vulnerable to their enemies attack.
Europes forces joined just this once to take out a common enemy. The Asian countries were attacking the west cost, canada had an easy target and so did South America and Mexico. Africa were using their air power to destroy the American cities.
We're all doomed >.>
