The problem as I see it (as an armchair theorist), is that if and when the US does eventually get into an air war with a foe that has a credible air-to-air capability, whether it be 10 or even 20 years from now, the US will no longer enjoy the necessary assets to fight from a position of either numerical or technological superiority.
While I agree, that a large part of the current US defence budget, should go to funding the two wars presently being fought and making sure the troops on the ground have enough of the right type of equipment, an eye also needs to be kept to the future.
This is especially true given the typical long lead times for developing new warfighting equipment.
Just my two cents as a Brit.
Heh, perhaps the US will end up buying Typhoons in the future to make up the shortfall in their air to air capability.
