Any they should pay their fair share. America is not the world's police.
Trump is very clever to bring up the Russian pipeline project. That has been a sore point with some EU nations when I lived there. Angela Merkle cannot respond effectively as Gerhard Schroeder is on the Board of the pipeline company.
Germany has made itself dependent on Russia and yet they complain of Trump's relations with Putin.
He is saying, we pay to defend you and you go and cozy up and make your nation dependent on the "enemy". Trump want's to call the shots in Europe and he does have support in certain quarters. He knows how to pick a fight!
BTW, Trump will win with SCOTUS, Muller will need to wrap up and those illegals will be sent home, with or without their kids.
Long after he has left this earth, Trump will be a Harvard case study on how to upset the apple cart.
When he done FRIG up this great Nation and all the Rednecks come out of their Trailers and stop humping their cousins, it will be TOO late!!!
One needs to understand the background on how the pipeline from Russia is servicing the various nations in Europe.
One also needs to view Turkey's development for the supply of gas to the countries in the European area.
