Nuke test!
My first thought.
Average magnitude of the Indian nuclear tests:....... 5.0
Average magnitude of the Pakistani nuclear tests:..... 4.9
The magnitudes are similar for two of them, except the 6.0 would equate to about a 45 kilo-ton bomb which seems too high. One would expect their first tests to be in the 10 kilo-ton range. Of course, they could always buy nukes from a nuke member and test it for the hell of it during their military exercises they are conducting now. You never know what crazies are going to do.
My guess is these were just earthquakes, even though the magnitude is similar to a nuke.
Look for Bush to give Iran more taxpayer money to build more IEDs to kill troops with or to build their nukes. Bush gave them taxpayer money after the Bam earthquake and after the other earthquake that followed Bam.
Truman never gave Japan money, now did he.
