Waw, harsh game for the allies!
So if England falls, USA better gets some DD blockers in the Atlantic.
Although, if England falls, isn’t the game usually over?
The American player makes a lot of money and can easily defend aganist Germany. He should have built a fleet to block the way to the American mainland. It clearly was badly played. America has no standard builds but instead needs to build based on what is going on. He could have built a bunch of Battleships and destoryers to bar the war and also built guys and tanks to defend the mainland. The other issue is that America should rarely play defenseive. With their IPC count they can easily afford losses that would cripple most other nations. A 1-1 trade is a win for America.
Even if the UK falls most of the time the German player looks to Russia cause its a lot easier to go there then to build massive amounts of transports to go bother America. I have seen America take back a conquered UK from Germany before. Its not easy or cheap but they can afford it.
