It's being reported today that in addition to advanced US weaponry now in the hands of ISIS, they also have taken control of as many as 2,000 Humvee's. So now not only is ISIS well armed, they are highly mobile too.
Way to go US! Why did we leave 2,000 Humvee's for the Iraqi army anyway? Probably for the same reason we invade third-world cesspools every 10 years or so, to get rid of aging ordinance, to field-test new weapons systems, and to keep our defense contractors at home flush with taxpayer money.....money that politicians know will somehow find its way into their re-election campaign chests.
I realize not all politicians are that corrupt and many naively believe that we are doing some good, but other than the time we liberated under-achieving medical students from thugs in Grenada, when has it ever worked out that way?
