It figures you would ask for details.:)
I don’t know, but I can wildly speculate like everybody else and see what sticks.
1. Perhaps the US is overextended with Iraq and Afghanistan, so it’s Europe and Russia’s turn to deal with the mess
2. Get Russia to deplete their warchests and manpower
3. See and evaluate Russia’s military in action
4. Undermine Putin in front of his countrymen
I’m sure there’s more, but that’s off the top of my head.
I’m thinking Putin may send his flying clown show over the Mediterranean.
