And what about the USSR and its "alliance" in the form of the Warsaw Pact?

They plundered the economies of Eastern European countries—first by directly stealing whatever they could, and later through trade conducted using the so-called "transferable ruble." This currency was used for the cashless settlement of trade (exports and imports) within the Eastern Bloc. Prices and exchange rates were set artificially by the state rather than by the free market—meaning that outside the Eastern Bloc, it was an artificially concocted currency worth absolutely nothing.

And if anyone didn't like this forced "alliance" with the USSR, the Soviets would simply roll in their tanks to replace the government with another, employing massive violence—as seen in Hungary in 1956 or Czechoslovakia in 1968.

But if you're talking about the Bourbon one then Spain got Louisiana out of it for a while while France got idk the guarantee that Spain wouldn't be led by a Habsburg and little less.

And why would they bother doing that when they already basically control the country?
