USA wanted to send nuclears all ready to destory by surprize first mover attack the russia.
Russia has no dedection system wich show's incoming nuclear attack If long distance from usa then might be but If from submarines then the attack could launched fast.
Off course the neighbours around russia was going to be sacraficed but at least the target country will be destroyed so USA can take that loss in order to save world peace and harmony
However there is just one thing why USA did not used nuclear attack on russia top military people knows about and it's secret but not very secret however finland even the sweden and Baltics should say thanks for russia for this one what russia did to stop USA using nuclear together with UK and france.

If we take usa nato Putin all together and record video and we ask all of them their agreement documents and we ask questions them to answere to us exacly then we would see what's going on but off course some of the countries not gona agree to attend this because Im sure some people wrong doings Will become in day light.
