I would say that a decent Allied player should not fall for this, but on G2 you buy 10 transports for a Sealion feint. In order to distract America, Japan might hit Hawaii on J1 or J2 just to make the US purchase heavy navy in the Pacific. On G3 you hit Gibraltar and SZ91. This sets you up for a G4 Quebec hit or depending on how America purchased you could hit any number of zones.
When America was stuck with only minor ICs before they went to war this was actually a lot more viable. America can easily respond with 10-20 infantry in Central and Eastern United States when your G3 surprise hits.
It’s a very difficult strategy to make viable simple because of the sheer number of troops that the US can pump out turn after turn to destroy your invading force, of which you cannot really replenish.
Unless you can take Washington, don’t expect to hold your ground for more than 1-2 turns.
