Well there's the rub for me. It's the definition of "threaten us". If the world were still armed with muskets and square riggers it would be easier to know who is a real threat and who is not. But even then, people like Thomas Jefferson who I don't think was a globalist deployed troops to far off lands that he was convinced "threatened us" and our trade.
Thomas Jefferson deployed troops to far-off lands to fight Islamic pirates who attacked American trading vessels and kidnapped and enslaved the Americans on board. He didn't invade Morocco, Algeria, etc., to attempt to "bring democracy" to them (he'd actually cringe at that term) as a response to a sincle act of terrorism followed by Islamist finger-waving. It's not just the sophistication of weaponry that was different in those times.
