This is true; in fact they are so concentrated on their provocations that they've missed some truly stunning openings that their opponents could use. They are ignoring a very important piece in the aftermath of their win in Arizona vs US, that the state could mobilize its military-powers and violently expel the invaders, indeed that is the only option left for states to enforce immigration.
If the Governor of AZ were to declare such an invasion, calling out the organized [National Guard] and unorganized [general citizenry] militia with shoot-to-kill authorization then there would instantly be a political shit-storm on the national level. {Arizona has enough evidence to prove invasion, I believe.}
Then, the governor is perfectly positioned to place the Federal Government into its own no-win scenario: demand federal [armed] assistance under Article IV, Section 4, of the US Constitution:
The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened), against domestic Violence.This places a not-insignificant portion of the political caste into a big bind, they have so wholeheartedly thrown themselves into one-world-government/no-borders scheme of things that to render aid would be seen as anathema and backsliding. Further, stalling [or denying] on such a request/demand would only add to the dissatisfaction of the states and serve to embolden the Tea Party/Constitutionalists in their criticisms of government. Lastly, should they act against the state they themselves will be committing treason, as defined by the US Constitution, to wit: giving aid and comfort to the enemies of the states.
In the not-impossible scenario that the federal government were to attack such a state, there would be undeniable proof/justification for the armed rebellion it would spark.
And if it doesn't happen naturally, they might give it some "help." See Fast & Furious, where the Obama regime already crossed the deliberate mass-murder-for-political-gain Rubicon.
Indeed, I can easily imagine a "false flag" operation for doing exactly this. In fact, it would be absurdly easy to do given the segregation of military and civilian law enforcement. Imagine setting a known-loyal military unit on a [say] DEA unit where one wipes out the other; the news then shows the resultant casualties and the "obvious militia" forensic evidence (which would obviously be planted/scrubbed). If nothing else, Fast & Furious shows how little regard is placed on civilian lives and safety.
A million Reichstag Fire scenarios come to mind. I alreeady wrote a novel about a false flat “assault rifle stadium massacre,” so they probably will not use that one.
