Next, following 9/11 the U.S. occupied Afghanistan. Outsiders provided weapons to the locals who wanted us to leave. Eventually - twenty years later - we left.
Now Russians (no longer Soviets) have occupied a fair bit of Ukraine. We are providing weapons to locals who want the Russians to leave. History suggests if we keep supplying weapons, eventually the Russians will leave Ukraine.
Two ways Ukraine turns out differently. If we tire of supplying weapons. Or if the locals tire of fighting for their own country.
Meanwhile, Russians are spending and dying while we are just spending. I know which side of that equation I prefer to be on. Daily Mail (U.K.) reports 100 Russian colonels have been killed in Ukraine.
Ronald Reagan outspent the Soviets and they eventually collapsed. It is to be hoped current U.S. leaders share his foresight.
