The only way a war with Iran can possibly be avoided.
First Iran would have to have basic human rights that would essentially demoralize an invading American Military force, such as the following:
1. The right to bear modern firearms, and ammunition for all citizens.
2. Freedom of Speech and Press, also including the right to remain silent.
3. Freedom of Religion and non-violent customs.
4. Equal rights for ALL that set foot on your land, this includes, curds, blacks, Jews, Muslims of all denominations, Christians of all denominations, gays, cross dressers, Arabs, mud people, women and men.
5. The right to Life, Liberty, and the pursuit of happiness.
6. Laws that protect children and family members & friends against reprisal or revenge or punishment. ( The United States is Slipping away from this, but you do hear about people getting shot for messing with others or attempting to cause harm to children. )
7. Laws that promote healthy money earning and spending competition, for the purpose of preventing losses or poverty to even a single person or family.
8. The rights of the accused, the rights to a trial by a jury of your piers and the right to wave that right, the right to a speedy trial and the right to wave that right.
9. Law that prevent local, state, and Federal government or legislatures from passing laws that infringe on all the above laws and rights.
10. Laws that allow the people to decide policy.
If laws like this were in place before the Mighty American Empire invasion, soldiers would just simply refuse to attack, or even switch sides as soon as they arrive.
But if your leaders actually did pass laws like this it would most defiantly bring the result of there own swift deaths and no invasion would be needed.
The only way laws and rights like this would possibly be passed in Iran, the following would have to take place:
1. The Iranian military would have to arrest all government officials including the Iatolas.
2. Round them up in a concentration camp. ( Not world war 2 style, when I say concentration camp, I mean a place where these people can collect there thoughts. )
3. They will be TOLD to and forcibly made to sign these freedoms into place, and also TOLD that there signatures or brains will be on these contracts, and since they were signed PRE DECLARATION of the signing, ALL THE LAWS WILL BE VALID.
The above must happen, if it does not, all Iranians should learn the Jewish and American pledge of allegiances ASAP.
