Absolutely in agreement with about the country being bigger than the government, the military or any individual. National anthems and flags are symbols that represent a country (not the military, government or any individual). But You may take some flack from normal allies for undercutting a couple of positions on this page.
I'll take this as a concession from from you (in your way of doing such things) that you were off base on why people stand for an anthem and why they sit.
