I think you put way too much value in the "solidarity among comrades" thing, Foxi..
I am a veteran.. and I have spent a significant amount of time in both Iraq and Afghanistan.. I have heard "bullets whistle" as you describe...
While I respect what McCain did while serving in the capacity as a US Navy officer.. I have very little respect for anything he did after that..
Just because McCain served honorably.. does not mean he is (or is not) an honorable man.. I know plenty of military vets I would chose not to associate myself with.. or attend the funeral of.. that proved themselves to be warriors, and left military service with an honorable discharge..
But.. thats another story...
What I find interesting is... some people in this country (and abroad) find it appalling that Donald Trump will not be attending John McCains funeral.. knowing well that these are two men that openly disliked one another and had very little common ground between them...
But those same people think it perfectly acceptable that Barack Obama did not attend the funeral of US Supreme Court Justice Antonin Scalia....
While Obama and Scalia clearly sat at different ends of the political spectrum... Obama was a lecturer on constitutional law at the University of Chicago and is a self proclaimed "Constitutional Law Professor".. and never had a personal beef with Scalia on anything... Scalia served on the US Supreme Court for 30 years.. and served his country in a variety of positions for 46 years... many would tell you Scalia did more during his career to influence and provide guidance and direction to the USA during his service than McCain, Trump, and Obama combined.... and yet, Obama did not attend his funeral..
How is POTUS Trumps decision to not attend McCains funeral any more or less of an issue than POTUS Obamas decision to not attend Scalias funeral?
Something also that should be noted....
McCain made it pretty clear and public that he did not want Trump to attend.. and while on his death bed was still hurling insults at Trump...
Does that excuse POTUS Trumps comments? No.. clearly not..
But it is something that should obviously be taken into consideration...
