Yeah,like the title says.
What will happen?
Why...........................how. The french were bound to lose new france. They were also bound to lose in India. As for Europe they may have been able to beat Prussia with Austria and if Russia hadnt betrayed them. The best I can see is a negotiated peace for france at the time. New france goes to Britain like otl, however perhaps their is slight border changes in europe. You could see a partition of Prussia beetween Russia, Austria, and France so as to end it as a credible hreat.
The problem is France could win in Europe but they 4 the colonial war in essene so not much really changes.
