Ok. The Russians won't even denie, that it those missiles were made in Russia. They will laugh in your face and say, that those Russian-made missiles were given to Yemenis exactly to help them to fight American aggresion, and it was Yeminis hand that turned the key (while the list of targets and all other preparations were made and authorised by Russians).
After that - will you attack Russian cities immediately, without even attempt to protect your civilians or attack Russian nuclear forces to decrease their retaliation?
