What is the longest period the Americans went without their armies being engaged in war with someone?

Be it native Americans, Mexicans, Spanish, Germans or whatever. When was the Pax Americana?

UM, as long as we’ve been around, almost like other countries like say, Great Britain?
Wish we were not, but WWII warranted a res ponce don’t you think, as did WWI, we can disagree with what is happening today, but please don’t forget we (the U.S.) is not ALWAYS the one who starts a war, WWII, which we were not even going to get involved in is one example.
I wish you well, and all of your American friends do too!
Have a wonderful lovely day and make someones day by doing a random act of kindness for no reason at all. Kind of like calling your best friend?
Blessings.
