The US caps the Sunni militia at 100,000

Amid all the Shia charges that the US's "concerned citizens" program was a mask for building an organized, competing Sunni militia, I find it interesting that there is a US goal/cap of 100,000.

This would put the "concerned citizens" (Sunni militia) right on par with the Mahdi and Badr Corps (Shia militia,) but not any bigger.
