If you are a civil servant or a Military officer , NCO or enlistee.
Yes definately.
The military is the servant of the government and sworn in loalty to the Constitution.
If orders are Un-constitutional or unlawfull they should be disobeyed , but this is a hard decision.
What Attitude should the servants of the people have in reguards to the orders that they get from the government?
The people controll the government , and the government controlls the military , what other arrangement could we accept?
If you are a citizen ?
Yes definately.
The law of the land is the product of the Congress and the State Legislatures , it isn't possible to craft law that everyone agrees with , but it is reasonable to expect a good level of obedience from all good citizens , includeing those who disagree with the law.
We have this gooing on pretty well , and if we didn't , could we tolerate dissent?
