Pense got even more silence and a shocked look when he tried to convince them to support sanctions against Iran after blowing up the nuclear deal that most other signing nations want to abide by. That was a great deal that took years of negotiating to stop Irans nukes with extreme inspections lasting for over a decade. So now we could have Iran going nuclear as well as N Korea whch will never agree to give up their nukes but has Trump patsy totally taken and out of his league.
Sadly many countries look more to Russia and China as more trustworth and reliable then the U.S. We need Biden or someone similar to reestablish trust and relationships with our ally's not our enemies.
The Russian missiles deal is more complex since Russia has been violating it for decades. But we are now moving into more a cold war nuclear era of the past with Trumps dear pal Putin who Trump trusts more than U;S. experts.
