That's the kind of approach, which allows 2nd world weak hyaena (which Putin's mafia state is) terrorize the world. “They stated, they will go nuclear”. Russians are not any nation of Ivan Dragos, ordinary folks over there shit their pants thinking about nuclear war, just like anyone else and their “VIPs” could actually panic If only they and their families were cut off from tropical vacations, western education, Swiss banks and latest smartphones.
Okay fine. Lets assume the big bad bear is just lying like Saddam Hussein lied about WMD. The US cronies claimed the reason there was no WMD in Iraq, was because Saddam had to lie to keep his neighbors in check. Because the Middle East is a big bad place with scary neighbors. So the new crony line is, do not worry about Russia going nuclear, because the bear is just lying to scare his neighbors. Have fun with that one.
