Don’t think they signed the last treaty. Missile testing?? We test them. Why can’t they?
“We test them. Why cant they?”
IIRC, this is about intermediate range ground-based missiles that threaten our European NATO allies. The US gave up testing and deploying such weapons in exchange for the USSR doing the same.
Back in the hapless Carter Admin the Rooskies were intimidating our NATO allies with the SS-20 intermediate range nuke missile. If the USSR got off a first strike and NATO weapons weren’t available to retaliate in-theater, the war would be over before the US could retaliate with more remote weapons. NATO allies weren’t confident that a weak US president like Carter (or currently Barry) would initiate mutual assured destruction if Europe was already fried and the Russians were stoking that fear.
At first Carter countered with the neutron bomb, but after key NATO leaders stuck their necks out and backed it, Carter backed out leaving they with the political damage coming and going and leaving NATO exposed.
When Reagan got in he countered the SS-20s with the Pershing, IIRC. (don’t quote me) as well as air-launched assets. Then when Reagan backed Gorbachev into a corner will our military build-up combined with collapsing the world oil price killing Soviet hard currency, the 1987 treaty was signed signally that the USSR was backing down from intimidating NATO unilaterally.
