First, a little history.
Reagan won the cold war by being both tough and honorable, then getting the Russians to trust him by offering the Star Wars anti missile technology to them, for free.
Russia would be as protected by their own military as we would be by ours.
Since then, the US Government has become the world's most dangerous untrustworthy backstabber, and the Russians know it.
We may not have the opportunity to try your idea, even if the Homofascist Progressive Socialist DemoRat regime would allow it.
In any case, we must wait until the Russians determine the cause of the crash. It may not be an ISIS MANPAD (altitude), worse it may be a bomb planted by a Soros funded, Ukrainian Maiden Fascist terrorist before takeoff.
Gorbo wanted Reagan to scrap SDI in exchange for a deal at ReykjavÃk, and Reagan told him to piss off. A little history.
