I think its more of a problem of people not using the humvees correctly. The vehicle itself is a good vehicle but not for combat situations. I'm surprised more hasn't been done since the Battle of the Black Sea in Somalia, 1993.
I'm not sure what aircraft the author is talking about I'm assuming the F-22 but it would be able to greatly help the United States. Often a lot of the attacks against terrorists has been done by airpower and that is why the F-22 could help with this. Also the fact that its stealth would help if the United States were to invade another rogue nation like Iraq. Not to mention they have spent so much money on it before. Regarding the Stryker I can't say too much about. It doesn't sound too good but I bet its probably better than I think it is.Meanwhile, we have the Pentagon spending billions of dollars on irrelevant gold-plated fighter aircraft and on the lightly armored Stryker a vehicle that is not battle-tried and that the Army has placed in relatively safe northern Iraq. Not to mention the thousands of potentially lifesaving armored personnel carriers M-113s left over from the Cold War gathering dust in depots.
