The M1 entered service in 1980. That would be under Reagan, and the program itself started in 1972; continuing your predecessor's program when it was literally the only game in town is not 'pro-defense'. So did the AH-64, M270 MLRS, and M109 Paladin. He also decided an already-obsolete bomber and cruise missiles would be sufficient for a nuclear war with the Soviets. (Hint: Would not have been) and managed to paint himself into a corner by pinning the public deterrent debate on the B2 years before it even flew, let alone became operational (that happened in 1997 ). He also publically stated that US troops would be withdrawn from South Korea, furthering a global view that the US was withdrawing on itself, which probably encouraged the Russian invasion of Afghanistan in 1979. Dude just didn't know what he was doing. I agree that Vietnam did impact the Dems, but not nearly to the extent you're saying it did, and also pretty negatively.
