Good argument, much better than the people who argue "hurr durr they'll nuke you" or "everything's a CIA honeypot". But you're still wrong, and here's why:
>1. "In peacetime.... like the jews or muslims."
This is true, and the PNW's current predicament. At the same time, however, it's a strength. Why do I say this? Because needing to move to the NW means only very committed people are able to join the movement. If laziness or lack of devotion is the reason they don't move, we don't want them. Lack of money and opportunity are somewhat of a problem, but the NW is a big place, and a potential migrant is bound to find some place cheap enough to live with jobs available. If that's impossible, then it should be known that there are other NatSocs that have moved, and are working on setting up their own businesses as to employ other migrants.
>2. In wartime a concentrated center of Nationalists... doomed.
The simple answer to this is not to concentrate. If and when a NW independence war happens, it will undoubtedly be a fourth generation style war, one where ZOG's toys will be ineffective.
>3. You're assuming the enemy will just sit by and let it happen...
Of course we'll be met with opposition, but as will any movement that opposes the government. If you want to get rid of ZOG, then risk of infiltration is something you'll have to do. There are preventive measures you can take, however. Kick out anyone who suggests illegal actions before any war starts, and make sure you know, and that you're friends with, everyone in the movement you're connected to. Remember, the alphabet soup agencies don't have unlimited resources, if you're unknowingly friends with a full time glower, then eventually you'll catch on somehow. Maybe their cabinets in the bathroom won't have any medicine, maybe they have a suspicious amount of disposable income, or maybe you just get bad vibes from them. And as I think someone in this thread mentioned, a glower will never, ever, let an evil nazi meet their wife and kids.
As for the "importing non-whtes" thing, I'm not to worried. Millions of non-whites would offer far less resistance to a nationalist takeover than you'd think. Remember, these are nogs we're talking about. They're not a race known for their bravery. If a government is oppressing them, and trying to get them to leave, and right next to them is the USA, willing to give them a lifetime supply of EBT and free housing, it's pretty clear which they'll take.
>However if there is a large nationalist population in the NW.... make it difficult to move from state to state (bring a law making it necessary to get paperwork if you want to switch states).
This would be unironically a blessing for the movement. If you look at history, you'd notice that these kind of crackdowns on nationalism very rarely work. For example, look at British Ireland. There was the Easter Rising in 1916 , which was (at first) a total failure. To oversimplify, a ragtag army of Irishmen decided they didn't like the British, so they took positions in Dublin, and proceeded to get crushed by England's armies in about a week. Most of the Irish were neutral, and didn't care what side won. Then the English violently executed anyone connected to the rebellion, and sent in a brute squad known as the black and tans. Three years later, a far more popular revolt broke out, and this time it didn't fail.
My point to this historical anecdote is that harsh treatment by the state and taking away a population's rights, is usually ineffective and in a rebel's favor. For more examples, see: The Troubles, The American Revolution, Afghanistan, The Communist Takeover of Vietnam, The February Revolution, and a just about every successful rebellion.
