ground vehicles and machinery it supplied to the Soviets during WWII via the Lend-Lease Act?

1. No, but they're all scrap metal now.

2. So western Europe isn't dominated by a murderous, fascist regime bent on world domination.

It was a worthwhile investment. The Soviets bled Nazi Germany white so we didn't have to.

3. Yes.

The final payment by the Soviet Union was made in 1972. (The final payment by the UK was not until 2006). Some Soviet gold payments during the War were sunk by Germany in the Atlantic but the bars were recovered in the 1980s.

4. Yes.

But not the stuff prior to 1920. But you can't really blame them for that.
