"The Cold War
During the Cold War, the Monroe doctrine was applied to Latin America by the framers of U.S. foreign policy. When the Cuban Revolution established a socialist regime with ties to the Soviet Union, after trying to establish fruitful relations with the U.S., it was argued that the spirit of the Monroe Doctrine should be again invoked, this time to prevent the further spreading of Soviet-backed Communism in Latin America. During the Cold War, the United States thus often provided intelligence and military aid to Latin and South American governments that claimed or appeared to be threatened by Communist subversion. This, in turn, led to some domestic controversy within the United States, especially among some members of the left who argued that the Communist threat and Soviet influence in Latin America was greatly exaggerated. (See Operation PBSUCCESS.)"

"The debate over this new spirit of the Monroe Doctrine came to a head in the 1980s, as part of the Iran-Contra Affair. Among other things, it was revealed that the U.S. Central Intelligence Agency had been covertly training "Contra" guerrilla soldiers in Nicaragua in an attempt to destabilize the country and overthrow the Sandinista revolutionary government and its President, Daniel Ortega. CIA director Robert Gates vigorously defended the Contra operation, arguing that avoiding U.S. intervention in Nicaragua would be "totally to abandon the Monroe doctrine". In a case brought before the International Court of Justice by Nicaragua, however, the court ruled that the United States had exercised "unlawful use of force." The U.S. ignored the verdict. The Carter and Reagan administrations embroiled themselves in the civil war in El Salvador, again citing the Monroe Doctrine as justification. The conflict was marked by large scale human rights abuses and the 1980 assassination of Archbishop Oscar Arnulfo Romero by right-wing death squads. The Monroe Doctrine was also cited during the U.S. intervension in Guatemala and the invasion of Grenada. Critics of the Reagan administration's support for Britain in the Falklands War charge that the U.S. ignored the Monroe Doctrine in that instance".

It would seem the Monroe Doctrine is used in to justify legally or illlegally what ever action we might at any time wish to perceive it needs to embrace. Legitimate IMO only in respect to the position that "might makes right' !

God forbid someone interject a bit of common sense into this discussion.

Gospel of Thomas

Not at all. The bombers can bear the interceptor missiles, or ordinary high-accuracy missiles. As well as one boosting unit was dismounted from offensive rocket and it became interceptor for the shafts in Poland. US demands we trust America the shafts will contain interceptors, despite everyone knows that Minutemen-2 or 3 can be loaded there and deploy nukes to Moscow in 2 minutes. I'm sure, you have no questions about "trust the US" after what's been happening in the world.
The bomber and the interceptor rocket is nothing but mean of delivery. Delivery of what depends on the desire of the master. Americans must trust Russians that missiles on the board of bombers are interceptor missiles and even if they are nuclear they are not aimed on the US and don't pose threat to them, because the exactly same Rice tells to Russians. Ten God knows what missiles in Poland nearby the border of Russia against 10 God knows what missiles on board of Russian planes nearby the border of the US. Balance rearranged. If some crazy will shoot missiles from Poland, we can not intercept them and they explode dozen of cities in european part of Russia. But bombers on the cruse will immediately shoot missiles from the same short range, few will be intercepted, the planes destroyed, but few missiles reach the main US cities on the coastline. This is grim prospect, but it is better then wait until the US will corner us and start direct nuclear blackmail of my land and we will be forced to plunge into the terrorist war of nuclear jihad. Now we don't defend some virtual freaky ideology like Communism anymore, it is time when we will seemingly have to fight for the land, house, children and honour, like did our ancestors in Saint Fatherland War 70 years ago. I don't give a damn about future of humans on Earth, if the US will put the line like "World without Russia" with their preventive nuking approach, let then be no fucking globe.
