Germany decides not to restart unrestricted sub warfare, leading to no US entry into WWI. Wilson remains sympathetic to Britain/France, but cannot convince his countrymen to join the war.
In 1918, with no need to end the war in the west before the Americans arrive, Germany tries a different strategy. Some of the troops from Russia will bolster the front in the West and help build defences, the rest will go to Italy. On March 21, supported by a huge artillery bombardment and with stormtroopers infiltrating the Italian lines, a massive German-led attack crosses the Piave River. The Italian troops, already demoralized by last year's loss at Caporetto, rout and this time don't regroup. The British and French troops sent to help fight bravely but are overwhelmed. Within a week the German and Austrian troops have reached Venice and within another week they have taken it. The morale of Italy is shattered, the country is torn by civil strife, and the government sues for peace at the end of April. The treaty gives Venetia to Austria and Libya to Turkey.
So what happens now? Austria can concentrate on the worsening front in the Balkans and might be able to slow the Allied offensive there. And Germany can stay on the defensive in the West while preparing for a big offensive in 1919. The British offensive against the Hindenburg Line will probably still be successful but it will be much bloodier than OTL and Germany will likely have prepared positions in the rear. Is a German victory, or even compromise peace, still possible?
