Obama screw's up

The Russians will protect Assad, the Russian navy are on the way to set up a missile shield, any strike on Syria will fail, he has left it to long, I suspect this is part of Obama's plan to waste time, while looking for an exit option, the Russian's have just gave him one, If the USA strike and Russia stop's the missile's Iran will laugh at any attempts to stop any plans they have. The US run the risk of looking very weak.
