Well said secretary @marcorubio 

The biggest threat to NATO as always been lack of commitment by the Europeans. If they are increasing their spending, great, they just made NATO stronger, what Trump has been asking him since he was first elected in 2016. 

Plus the Europeans must understand that trade, technology, FDI and defense must be part of the same alliance, and China and Iran should not be treated as isolated threats, the Europeans facing energy crisis due to their own bad policies moved more than 500 billion dollars worth of manufacturing to China that are going to boost the Russian military industrial complex when the United States offers a much safer environment and much more secure energy for investment in industries such as chemicals and component manufacturing and the biggest market in the world. 

If we are defending Europe against Russia, do we have the same commitments from the Europeans to defend us against China (or China and Russia together giving Europe the choice of neutrality in a war against America) in a possible future war?
