I was under the impression that the tribute amounted to something like 15% of GDP. No small tribute, I don't know how that would relate to naval costs but I can imagine that outfitting a force is much cheaper than paying 15% of GDP to a foreign power. Once Federal debt is under control I can't believe that the Govt. would stand for it.
Morocco? what have they got to do with it? is that were the deposed Sultan went to after his brother threw him out? In the 1790s is he still in charge in Derna (OTL Tunis)?
Weren't they a Barbary State or at least allied to them?
Yes they were my bad. I thought you meant they were a US ally. AFAIK the raid and occupation of Derna pretty much wrecked the Barbary states and that was really the only thing the US had to do. One and done if you will. Is there more to it than that?
Not related to this TL, but for some reason, your font size is tiny. It's hard to read. I'd suggest you try figuring out what the problem is and fix it.Depends if an American force can win this time around or earn the aid of their ally Morocco.
