I still have not seen you back up your opinion with any sort of real world example. Instead of me proving you wrong with countless other examples, how about you show me one example where congress has stopped a military operation with funding cuts, or the supreme court with judicial rulings.
You seem confused on history, the record is one of Presidents going to Congress over large scale military operations not avoiding it. As for the Supreme Court there again we have the record of history saying the Court does have jurisdiction over the military to ensure adherence to the Constitution.
History has proven time and time again that these ideological checks & balances are not working as well as they should.
Actually history shows Presidents, Congresses and Courts agreeing to make the same mistake, as in the Japanese internment case. That is something quite different than checks and balances not existing.
