Invade Florida and just get established before a cat 5 hurricane smashes into them. Cross through Cali and you are in a huge desert. Alaska is mostly empty land. Then add over 1 billion guns and that's just the private sector. And of course after our Navy and Air Force.

Alaska is mostly empty land, but that empty land is rugged wilderness, completely unfit for military logistics. Might as well try invading Brazil through the Amazon.

Plus the Alaskan public has been pleasuring themselves at the idea of an invasion for decades. You think Texas has lots of guns? Alaska is higher per capita.
