No.
Hawaii should be gone, as well as Puerto Rico and all other islands.Indefensible parts of the border with Mexico should be ceded back to them.
On the flip side, we should push for access to the gulf of California in the south, and we should just invade Canada (again), take over BC, and join Alaska to the rest of the USA.. We should extend the northern border to the St Lawrence Seaway and all of the coasts of the Great Lakes as well.
