@Imperious:
The interception by the British might have brought the US in a few months earlier than they would have come in with out it.
Right it was the trigger for US entry in the war. The actual trigger. Since USW was also considered a second time and war did not occur, the Germans were hoping no war would be avoided a SECOND TIME.
and V1914 do not reply.
IL as you know, at this point (1917) the Germans were in a stalemate, and on a backward slide (allies were gaining strength in France). The Germans wanted to cut supply to England, and reinforcements coming into France. They were going to resume unrestricted sub warfare to do so. They tried to entice Mexico into the war (Zimm Tele) because they believed that resuming unrestricted sub warfare would bring the Americans into the war. They wanted the Mexicans to tie down a good size portion of the US forces, to delay Americans involvement in Europe (as they strangled the UK). Again they only sent the Zimmerman Tele because they knew that resuming the sea fight would bring the US in (as it did).
The decision to declare war was already on the table when Wilson severed all relations to Germany on Feb 3rd 1917, in response to Germany resuming unrestricted sub warfare again resulting in more American lives lost. It is thought Wilson didn’t know about the Zim Tele at this time, as the Brits stalled in passing it on because they didn’t want the fact that they were reading US wire exposed (they used this time to set-up a cover story). It is thought that Wilson got word of the Zim Tele the end of Feb, but when released to the public many thought it a hoax (so public opinion was still mixed). Zimmerman himself set the record straight to the press twice, the later being Mar 29 1917. Congress DOW on April 6th. I agree that the timing of the Zim Tele might have been the straw that broke the camels back (added evidence), but by this point the writing was on the wall.
It was more like 2 prize fighters standing off waiting for the bell to ring, and when they meet in the center to shake hands (before the bell), one of them slaps the other in the face. This starts the fight a few seconds early, but it was going to happen anyway.
Sorry this is a bit lengthy and also off topic, but I guess I took the bait too LOL (I won’t continue this debate here, so I guess IL will probably get the last word so he will think he’s right)
