[X] The Cabinet had a counter offer, formally asking that Canada join the Civil War on their side, launching military operations against the CSA, and in return when the time came to retake the Isles, the US would play an active role, essentially joining the Entente.
People do realise the Economic superpower USA will become right? Syndie France and Britain will have 0 chance of stopping us when they're facing off against the Reichspakt this eliminates two foreign powers that actively work to sabotage us internally and externally and replace them with two friendly countries deep in debt and needing money to pay for reconstruction, this is how America became the world superpower OTL.
Also for those worrying about how this will make the US look, don't, because the US already has got 0 reputation left as we just split in three and other countries are taking our stuff, joining the Entente is useful as we have overseas muscle to back us up and watch our stuff while we fight the syndies and racists.
