It would be the stupidest thing they could possibly do. The war has like a 20% approval rate. If they attacked on American soil the cowboys would flood the enlistment offices.
These seem like a good idea at first. Then you realize the amount of work it takes to maintain the land. For farming you need good soil conditions, water, keep pests and weeds away. By the time you've done it all, you will have made food that has to be sold for 5x - 10x the grocery store prices or you're paying yourselves like $3 an hour. You're literally better off working a minimum wage job and buying grocery store food.
If you aren't trying to farm and just want to do the commune thing, land maintenance is still work. Theres reasons suburbs are all paved, nature is always trying to retake whatever it can reach. I have just a few acres and I constantly fall behind on maintenance tasks. I have a career and a family, and the land keeps being the thing that falls to the lowest priority.
