Discussing a Free Society

I've been reading a lot lately about free society and the American Constitution.  Meanwhile, my daily bible readings for the last month have been concerning the Levitical Law, which dictates a theocratic government with God at its head.  I've heard it said before that the USA was built on Judeo-Christian values (which I do believe true to some extent), but our Constitution directly contrasts most of Israel's founding law.  I believe that our nation's current problems relate, in large part, to our failure to uphold the Constitutional values it was founded upon.  Let's take a look at some of the ways in which our nation was supposed to differ:

1. Separation of Powers  Levitical Law gave the priesthood full control of writing laws, carrying them out, and judging the convicted.  The United States Constitution separates the legislative, executive, and judicial branches in the hopes of preventing future corruption.  However, presidential power has increased dramatically, and Congress has essentially allowed presidents to pass unconstitutional laws through executive decree.  One example is the decree that anybody suspected of terrorist activity (even a US citizen) may be assassinated without a trial.  This essentially gives the executive branch all the powers of the Levites.
2. The Right of War  Israel was an offensive country for much of its early-biblical existence.  They went where God directed, and conquered great nations in the name of the Lord.  One of the most important examples of how the three branches of the US government are supposed to check and balance each other is the declaration of wars.  Even though the President is the commander in chief, Congress is in charge of declaring wars.  The last war declared by Congress was World War II.  Since then, we have fought wars in Vietnam, Korea, Iran, Iraq, Afghanistan, Libya, and many other countries around the world.  Most of these wars (including the 9/11 attacks) have been started by our own military intervention in those countries.
3. Conscription  All Israelites not in the tribe of Levi were considered part of the military if they were over 20 years old and male.  The US Constitution does not give the power to draft soldiers at all.  Our current conscription laws are unconstitutional.
4. Income Taxes  Israelites were required by Levitical Law to submit one tenth of their produce to the priests (their government) as a tax on their income.  When the US was founded, there was no income tax, and the power to tax citizens was not given in the Constitution.  This means that our income tax laws are also unconstitutional.
5. Healthcare  Israel had a centralized healthcare system, which consisted of going to the priest (government) to determine whether or not you were "clean."  If you were unclean, you had to stay outside the camp and not touch anybody until you were deemed clean and performed the cleansing ritual.  In the US Constitution, healthcare is not mentioned at all, nor is cleanliness.  Any federal laws concerning healthcare are unconstitutional.

The more I read about our Constitution and our current status as a nation, the more I fear for our wellbeing. We are being unconstitutionally violated in so many ways that I can't count them all, and for the most part the government has convinced us that they're doing it for our own good.  I'm not a government expert, but I know enough to see that our government today would scare the founding fathers into revolting again.

I don't know enough to say whether or not our government truly has our best interests in heart, but I do know enough to see that they are violating my Constitutional rights.  They're spending my hard-earned money on wars that were never declared against countries I've never heard of.  They're stealing my money and giving it to other countries through foreign aid, and to people in our own country through bailouts and welfare.

If we were the nation of Israel, led by God, I would trust that these things are all for good.  In a nation that is not led by the one true God, I do not believe it for a second.
