larry johnson makes a large point just in the first pargraph; 

Underestimating one’s opponent, whether it is a sporting event or a military confrontation is a recipe for disaster. If you watch the mainstream media in the West, you are subjected to a flood of claims by former military and intelligence officers about the weakness and incompetence of the Russians. If you take time to watch my interviews with Russian military correspondent Sladkov and retired Russian Colonel Basurin, they eschew making such characterizations of the West… The US military in particular. For them, war is serious business and requires that one respect the opponent.

The news that the Pentagon has approved shipping Tomahawk missiles to Russia is a potential disaster for the West. One thing I heard from most of the people I interviewed during my time in Russia is that the deployment of this weapon to Ukraine is a red line for Russia because that missile can carry a nuclear warhead. If President Trump decides to do this, and one or more of those missiles are launched into Russia, then the Russian response will be severe and is likely to extend beyond Ukraine. Because the Russians believe that a Tomahawk can only be launched with direct participation by US military personnel, I cannot rule out the possibility that Russia will retaliate by hitting the continental US if the Tomahawk hits a sensitive target in Moscow or St. Petersburg… Donald Trump is playing with nuclear fire...........more..........
