Furthermore, Germany had surrendered as it was promised to make peace on the base of the 14 points. They were betrayed. They would not have done so knowing the results.
No they weren't promised anything. Wilson corresponded with the Kaiser with the 14 points in mind. Never the French promised anything to the Germans (and never did Wilson also, as he never signed anything like that). The german generals who signed the armistice knew what would happened and they believed the armistice conditions were too harsh but signed anyway, because their country was disintegrating fast.
And the USA would likely not have continued the war.
Yes the US would have continued the war. They didn't enter the war only to leave it a year later without anything to bring back home : americans expect a just deal, leaving after suffering thousand of death and getting nothing is not what the americans signed for.
Your points are wrong.
Please explain to me how.
In which case no war guilt clause
There is no War Guilt clause and there was never any war guilt clause ! it is a myth created by the German right.
