Embargos and sanctions are covert acts of war against an enemy. An attack on an enemy is an overt act of war. The Congress is the only authority that can declare war of any kind against an enemy who attacks us. We have not been attacked by Syria and Syria has not even retaliated against the act of war perpetrated against them because they realize such action would end up in their annihilation. The same is true of Iran, Iraq, Libya, Panama, Cuba and every other state that is powerless against us. Even our sanctions against the Russians have not brought any retaliation. The reason is they either have no effect or they would exhaust themselves in a war they can not win. Ours is not a defensive military but an offensive one. One need only look at the types of arms and equipment we produce.
There must however be a dragon to slay because when you create a monster, you must keep it fed. As Machiavelli so aptly pointed out in his treatise "The Prince", if you allow it to remain idle it will satisfy its appetite by eating the hand that feeds it. Our monster is the military industrial complex and the army, navy and air force it supports. Its supplicants are everywhere but its food is provided by your taxes. Do you think the countries to which we sell arms are paying for them, even Israel? Saudi Arabia is perfectly willing to pay cash for our arms production but why don't we sell it to them? The answer is simple, if they are theirs, they owe us nothing and are therefore not beholden and the only thing they need after purchase is spare parts.
The irony is that war need not be fought when you can maintain self sufficiency by just getting rid of excess population. When the internal combustion engine, water power and steam power began to replace the horse we stopped breeding horses. When it began replacing humans we failed to stop breeding humans and we are very close to consuming the entire production of human fuel. This is not so in parts of Africa and the Middle East and even in Asia where countries are bartering raw materials and finished products for imported food. This scourge has not escaped the United States and we now import enough food to feed over 50 million and yet we not only continue to breed more humans but eagerly welcome millions more. Just ask yourself, if we are such a rich country why are there food banks and soup kitchens and organizations such as the Red Cross, the Salvation Army and Good Will?
