That’s not the US led UN backed war following Iraq‘s invasion of Kuwait. Iran and Iraq had a long and brutal war with tanks, planes, helicopters, mines, trenches, and more in the 1980s.
Near peers? Pretty sure there's a whole ocean separating Argentina and Britain, even if the islands where the conflict occurred were "just next door" to mainland Argentina.
It's a measure of military capability between nations. A Near Peer would be a nation that shares similar capabilities for force projection or in otherwords the powerscale is 1:1.
