Regarding the America first approach, I tend to think when Trump makes denigrating comments concerning long established allies, such as those in NATO, rather than strengthening the US position, or putting it first, he's actually weakening it. That kind of behaviour can only be good for Putin and co. The constant undermining and distrust of America's own intelligence services is deeply worrying and strange. That one agency felt compelled to investigated Trump to ascertain if he was either knowingly or unwittingly a spy or Russian asset is staggering - even Austin Powers knows he himself is a spy.
I think of all the things Trump has done and said, history will judge him most harshly on his complete refusal to accept or educate himself on the science behind climate change. The US military believe the science and view climate breakdown as the greatest of all threats to global peace and prosperity. It's a reckless man that gambles with the lives of future generations based on nothing more than a hunch.
I have enormous respect for you, it's a very brave thing to put your life on the line three times for your country. Maybe something you and I can agree on is that you have more courage in your little finger than the president has in his entire body. I'm not here to change your views either, but you, your country - the whole world, deserve far better than Trump and his administration. It's been enjoyable exchanging views with you in a civil way. All the best - except for Nov 2020!
