John McCain's biggest crime was NOT from his time in Nam...
John McCain's biggest crime was also NOT his conspiring over Ukraine and various Middle Eastern countries, conspiring against Trump, screwing over the American people in general, nor profiting from the corruption in govt.
His biggest crime is that he conspired in a globalist plot to ultimately destroy the US.
Remember the 2008 elections?
Know what's simiar about the 2 candidates, Obama and McCain (besides the overall corruption, criminality and hatred for the American people)?
This is the similarity that matters, and shows what he and Obama were up to:
Either of them, if placed in the Oval Office, would be illegitimate Presidents - from start to finish. Which means that every action taken as President would be illegitimate. Which means that their entire term - all laws passed, all appointments made, all executive orders, etc - would be able to be nullified and reversed in an instant, as soon as it is legally recognized that they were ineligible, thus illegitimate.
A reversal/nullification of 8 years of new laws and appointments, etc, would destroy our economy, as our current economy is largely based on existing law.
It would also discredit Congress, SCOTUS and the idea that the govt abides by or cares about the law.
Lastly, if the illegitimate President was "historic" and loved just for his race and appeal to amoral societal rejects, it is then very likely that a reversal/nullification of his terms would bring about a lot of societal conflicts, violence and possibly a civil war. The civil war becomes much more likely when compounded with a chaotic economy and a disregarded/hated government that is confused and has lost control.
McCain always knew he was ineligible, just like Obama knew about himself. McCain was born in Panama, OFF the military base, in a municipal hospital under which no soil could in any way be considered American.
That might sound like an irrelevant technicality or wrong due to his father serving in the military, but that WAS and still IS the law.
So, the globalists stacked the deck in 2008 with 2 ineligible candidates, in order to ensure that they would have a so-called "President" whose terms could be reversed overnight, thus causing the devastation to the US whenever they finally decided to expose the former "President"s ineligibility/illegitimacy.
They also followed up in 2016 with more illegitimates; Cruz, Rubio (some other Repubs too), Bernie (likely a dual citizen) and Clinton (violated 18 USC, section 2071). I think they did this just to have a plan B, in case they figured they needed to increase the number of illegitimate years/laws ensure the devastation they desired.
McCain knew that this was the plan the whole time and happily conspired to bring it to fruition.
THAT is his greatest crime. Conspiring to end the US and have its people kill each other in the millions.
