It is good politics or at least they believe it to be good politics to do both.
Our elites in charge of our foreign policy and the globalist crowd despite Russia and Putin. Putin has made it easy to despise him as well.

We will contract to replace the old stuff with newer and more expensive stuff and the campaign cash and PAC money will flow from the MIC as it always does.
