Not a chance in hell that a nuke comes from Russia or China. They understand that all of their cities would then be obliterated.
Terrorists on the other hand are religious fanatics who are far more difficult to retaliate against.
You can keep dreaming. This world is not the 1980s world any more. This world is getting worse and worse. Take time to read the Bible. It makes clear as a bell what is going on in these days and what is to come. Nukes are clearly spoken about. And our so called leader in the White House is rapidly cutting down our nuke forces as the Chinese and Russians are adding and helping Iran have them. Plus North Korea is a nut case state. This is not a world of safety any more. There are thousands out there who want to destroy this nation. Putin wants to be big man on the block. We don’t have Ronald Reagan’s anymore to show them we will stand up to them. The idiot in the White House now is disarming us. A military back to WWII levels??? That is inviting attack. Never say never friend. An enemy attacks when you are weak. We are getting weak.
