NIH syndrome does not good weapons make. Even the USA has been able to purchase foreign weapon systems when necessary. As for saving subsiding blue collar voters, Leos could have been built domestically.
Do the words "Not Politically Possible" ring a bell? Why, pray tell, should the U.S. Army and Marine Corps buy something foreign designed and built when American companies can design and build a main battle tank? The same goes for the British and French militaries and defense industries as well. Try getting your proposal for Leos in the U.S. Army through ANY Congress, even if DOD opposes it-as is likely. It wouldn't make it out of either the House or Senate Armed Services Committees no matter what. Ditto for the U.K. and French parliments as well. No chance at all.
I take it you've never heard of SA-10 and MiG-31, hmm? The B-52 would've been limited to standoff strike with ALCM in this case. The B-1 was needed as a penetrating bomber pending the arrival of the B-2 into SAC (at least that was the plan in the 1980s). Some targets won't be hit due to the missile platform being shot down or caught on the ground, weapons may not initiate over the target, and so on. And some targets required the accuracy that a penetrating bomber can deliver. A bomber that can survive in the Soviet Air Defense environment of the late 1980s a B-52 was not. The B-1, for all its bugs at the time, could.
And Peacekeeper? If it had been built as planned in numbers, but deployed in extra-hardened MM silos, then it's worth it. Hell, replace the entire MM II force missile-for-missile with Peacekeeper in that case. That's 450 missiles, with 8-10 MIRVs each.
I'll take 16-inch over any type of 8-inch any day. And that was what the USMC said in the '80s. NOTHING equals the bombardment potential of a battleship-even today.
