I should have been clearer
a Gov can not order a guard to stop or prevent federal agents from doing what the federal gov ordered thefederal agents to do
and a Gov can not order state guard to arrest or detain illegals the way federal agents can. A POTUS could of course give the guard the authority to perform same duties.
The federal gov has authority over a national border which is what the southern border is.
Do you think a Gov can countermand orders given by the federal gov?
I see what you’re saying.
What if Perry ordered the national guard to enforce the border laws? Not preventing the Feds from doing their thing (or not doing their thing, to be more accurate).
I don’t see how that violates the conditions you outlined. And it puts Obama in the spot of having to officially order the Guard to not enforce the border laws.
