Trump can piss right the F off! They could not win a war against us.

1. All our measurements are in metric they would just be lost.
2. We will cut off their power and the average US citizen will get mad because we give them so much electricity, at least the northern states.
3. We will cut off the oil tap and their military vehicles will not be able to run. At least until they reformat their refiners for their oil, leading to more power outs.
4. Their economy will just crash because of power outages. Leading to the people who would retrofit the refiners demanding for more money, that the oil companies do not have on hand.
5. The people will rise up in the US because of the massive and very fast inflation, Trump will be remembered as the president who destroyed the US in a mater of a few months of taking office.

I do not want to say go a head and try but the US loses either way, I also understand that there are military people way smarter than me who have battle plans drawn up. I did not know that these plans are kept up to date as well.
