Whilst spending my time on youtube, watching historical films etc, I stumbled upon the stuff about Germany offering Mexico to get back Texas and some other stuff in the southern USA.
Unfortunately (For Germany) the Brits got this info as it was sent, afterwhich they gave it to the USA, thus further pushing the public opinion for entering the war towards a "hell yeah!" in the USA.
So... my question is;
What if the Brits had not intercepted this?
Would the USA still join the Entente, due to the German action of unrestricted submarine warfare (which was, in the day, seen as cowardly),
Or would the USA concentrate their efforts on defending their own territory against the Mexicans (if Mexico joins the central powers?) ?
Uuuh... so much text...
