Consider for a moment, an enemy of the US, who has been postured into a position of leadership, controlling the Executive Branch of the government, who has conspired with other machinations on a planned agenda to either destroy te Constitution, or continue to take resources from the nation while weakening its worldly position.
Consider how a body politic, which had intended the demise of a Constitutional government for decades, finally came into controllable power planned within a decade, and began to prepare their operations during a window of critical vulnerability, generally associated with an outside threat to the US, but instead, measured the resolve of external powers to oppose their internal aggression, and then acted internally without any external intervention.
Such a grouping of malcontents, recognizing financial messes are most easily overcome by declaring bankruptcy and insolvency, than to remain fiduciarily accountable for their behavior, having planned for the financial debaucle of America over a 5 year period, would relish the opportunity to get rich quickly, while the already doomed economy was in their control.
Such a democratic socialist controlled government, would relish the opportunity to run up trillion dollar deficits, because they never had any intention of anybody ever being able to pay it back.
What would be the easiest way of paying the piper?
Simply not being able to resolve anything, throwing their hands up in despair, and letting the existing laws controlling government operation take control, and collapsing the government for them.
IMHO, only a very snide and ruthless leader would allow such things to happen to his nation, but then again, such leadership also has not exhibited moral or ethical virtue when tested in obeying the Constitution in situations such as Libya.
While it might appear lunatic fringe to suggest Obama would allow the US to collapse, it also would be amazingly consistent with his modus vivendi, the world history of key pivotal national moments, and recent international geopolitical events.
In a nutshell, even if Congress approved the budget and next years budget concurrently, does anybody really think Obama wouldn;t use this opportunity to his maniacal advantage?
