Germany would resume unrestricted submarine warfare in early 1917 & begin targeting American ships once more. This would be the final straw for the US & President Charles Evans Hughes would ask US congress to declare war on Germany on April 7,1917. Though the vote for war would easily pass many in Congress would worry about possible hostilities by the Confederacy with sending so many American troops to Europe. This worry would soon subside however when due to German attacks on Confederate shipping as well the Confederacy would declare war on Germany on May 21,1917. Though per the Treaty of Nassau the Confederate military was not to exceed 50,000 with Confederate entry into the World War against Germany both the US & Texas would drop the treaty term & allow the Confederacy to increase its military. However even with the ending of the troop limit the Confederacy would only send 750,000 troops to France as opposed to the over 2,500,000 US troops sent.
This is from a while ago, but a POD as far back as the 1830s will probably cause some major butterflies that will all but make the Entente disappear. Germany might be unified, it might not be. Who knows, it might be unified in 1848, and therefore won't be as militaristic as OTL's German Empire. You lost me at Charles Evans Hughes; he would totally be butterflied away. Things might happen in the Ottoman Empire that causes it to not lose land in the Balkans in the late 1800s, taking away the major reason for WWI's occurance.
