So, getting back to this:
Premis: If we have the USA in this from day one, then the USA must be in a formal military alliance.
If the USA is in a formal alliance, they need to have a professional, standing army.
Who is the USA mad at, and who are they allies with?
For me, the Germans did some historical things that didn't end in war, but could at least have been blown up in the press to carry more negative public opinion, so I'm going with a Franco-American alliance.
This gives us a clear need for the USA to be building a 'real' army.
If the USA is allied with France, and needs a real army therefore, what better model to use that the French one for universal conscription?
If the USA is going to be fighting a ground war in europe, how fast will the USA need to get her troops to France?
Given a start date in 1898, how long before the USA has an army equal to or greater than Germany?
If the USA is ticked off at Germany, will she pass her own naval laws, but perhaps the United States Naval laws might be timed to match Germany, but give us +1 BB over theirs?
This would give the USN an authorized strength of 20 BB in 1898, and then in 1900, 40 BB.
I have already detailed what I think the USA would build for an army in post #38.
