strange I don't recall america ever not beiing a republic untill the end of the north american war ( when another country can over rule a election, it is not a republic) and I seem to recall that england was the first one to use gas warfare in the battle of D.C (we didn't even have gas weapons for a good part of the war) and germany did send weapons, they didn't fight cause the were too tried of war. well I suppose the winners are the ones who write history.

True Ford was elected in 1924 fairly honestly but after his assassination and the take over by the extremists there was little but a reign of terror. You just have to see how many people fled the country in the years before the war. Let alone those expelled. Even with the continued economic depression its significant that the US saw its population drop during the decade before the conflict.
On the idea that the allies used gas 1st that's total garbage by the apologists for the defeated American 'Nationalist' regime. Britain respected the no-gas use until the Montreal attack despite the US not being a member of the Geneva Treaty. There are still people alive from the conflict along with plenty of records of incidents and memories after the conflict.
As it was Canada got off fairly lightly. While the occupation of the prairies was, like most of the ANP operations, brutal and thuggish, it did preserve them from the gas attacks. Most of the rest of the country was too thinly populated to be targeted and once the allies realised the threat they managed to provide some CAP over the other Canadian cities and keep them out of artillery range. The people who really suffered were the Latinos’ to the south. MacArthur's slaughter of the Cuban rebellion didn't even stop when the resistance had effectively ended and nearly 2/3 of the island's population ended up dead. No wonder that bastard hung after the war. While what the US 7th and 12th Army Groups did during their advance to Mexico city and the battle for the city. Utterly revolting.
Mind you, as the old saying goes, those who sow the storm. The US suffered about 35 million dead in the conflict and while that included several millions from internal massacres and the front line conflict the majority came from the Sterling and Doncaster bomber attacks. That was what really brought the empire down as it enabled the allies to cripple the still substantial US industrial base. If they hadn't developed nerve agents when the US started equipping its population with gas protection, or the US RDF network had been developed earlier it could have been an even longer and more costly war.
Anyway, back to the initial question. If the US had got involved in WWI then who knows. They might have gained some valuable experience that could have cost the allies dear in the early battle. It was only the quality edge of the Canadian and British veterans that enabled the eastern and western bastions to hold once the US extended the war against Canada in 1930. That could have been really grim for the world. Britain and Germany might have resolved their differences, which were fairly trivial, but if the dictatorship had conquered all of Canada and possibly Newfoundland and Bermuda as well, then it would have been virtually impossible to keep their pirates at bay, even with the edge the alliance gained in the early naval battles.
