Recall, in 2007
If a state really cared about "states rights" then it would kick the National Guard out. It would then replace it with a true state militia funded entirely by state revenues.
Then if the nation were to go to war that state could have a separate vote to see if their citizens wanted their militia to join forces with the national defense forces.
The state militia could be used to protect its borders from invasion by illegals, and any unconstitutional usurpations from the feds.
Of course the Feds would win a hot war, but in this day and age of 24/7 news cycles any hot war would be preceded by a cold one that could easily be won by an underdog militia threatening to defend itself against a bloated federal army.
