I say we just let them put up a fence around every blue area on the map. No reason to give them huge chunks of the country when they only occupy small spots.
When they ask how they will feed themselves just reply "Don't know, don't care"
We can charge tem obscene tarriffs.
I second the wall theroy. Living in WA the only place that needs to be walled up is the Seattle proper area. The rest of king county and the state are fine. Go by the county by county map and we are good to go.
