Well if you play with new players you kinda need a way to let them play their game while also learning them the game. Which is a fine balance.
Is this an optimal strategy absolutely not.
Does this give the US something to do that could be usefull, sort off.
Though it might be better to send them via canada -> UK and then have the uk protect the transports near the UK. it gives a double chuck but since its historicaly accurate and gives them the option to attack germany earlier. And you have to lead them even less, just say something like lets do it like they did in the war, move US troops to UK and then strike.
IF you are experienced and playing with new players expect to lose and just see the game as a fun time hanging out with friends where the game happens to be present.
