I do not trust my government at all in many things. That is why I am so grateful that we have our Constitution and the means to change elected officials when they abuse their duty to defend it. I think many of our elected officials are corrupt, dishonest, self serving and are far more interested in feathering their own nests than they are interested in being noble, honest, unselfish, or doing anything real that will honestly make things better rather than just looking or sounding good at the time.
I do trust my government in the sense that it is a rare politician who would think he or she can commit treason and get away with it.
But maybe you "haven't seen "severe reprisals from the people" when McCain said that, for all he cares, America could have troops in Iraq for the next 10,000 years" is because he intended and said nothing like that, at least as you seem to intend for it to look. Those with intellectual honestly know that he meant it in the sense that we still have troops in Germany. How sinister is that?
Some of America's critics are too often like some of our politicians that I hold in the least regard. They manufacture or repeat lies over and over trying to pretend they are true. And that is quite contemptible.
