Why America in always on the anvil?

Two things that define the 20th century world are Petroleum and USA. Of course the two things are intertwined; for hadn't it been Oil, America wouldn't have dragged it's foot in so much mire as it had. Personally speaking I, myself, am not a big fan of USA given that its the same country that sent its naval ship against India during the war of 1971 and its the same country that continues to fund Pakistan's military budget (even though implicitly) but the thing that has alarmed me in recent times is criticism of Uncle Sam from a select few countries.

I would be more specific here and point out to three countries - North Korea, Venezuela and Iran. Its rather funny to find that leaders of these countries- Kim Jong Ill, Hugo Chavez and Mahmoud Ahmedinijad are either dictators themselves or are running them anyways implicitly. There are blatant human rights violations in these countries, unstable financial conditions (except Iran, I would say here) but still the focal point of the leaders of these countries seems to be lambasting America on even the minutest of issues. whenever I think of this my naive mind can up with only three reason to explain rather abnormal behavior of these countries:

1. USA with its historical record is no hero in eyes of many a people and leaders of these countries want to thrive on those feelings to gain popularity. UK and USA were seen as main villain in Iran and were seen to be the guardians of the monarchy over there prior to Islamic Revolution in 1979. America's involvement in the Korean war and its "big Daddy" role in western hemisphere justifies hatred of North Korea and Venezuela. But take another of america's victims Vietnam- the country most savaged by USA and its belligerent policies. But this decided to move on and is presently one of the most thriving economies of the world. I don't say that Vietnam in any way has forgot the trauma of Vietnam war but it is focusing on rather more important issues now. The leaders of the aforementioned countries , on the contrary, still like to dig old graves.

2. USA provides a perfect shield for these leaders to shield their own shortcomings. Have a look at North Korea. The country still lives in darkness, literally, the only urbanized place is PyongYang, their capital, and most of its citizen living below poverty line. Few days back I saw a documentary where many North Koreans were shown making prior appointments for cataract operation and somehow they were made to believe cataract operation was more important and expensive than say cancer treatment. And in their ignorance those patients really believed in what they were said and thanked Kim Jong Ill, like God,for the operation. And in this country the only news that makes headlines is USA.

3. Lastly USA plays a perfect deviation for these leaders to carry out their black propaganda. Take Hugo Chavez for instance. This guy has been making many a attempts to land himself absolute power and infinite term but the only news we get out of Venezuela is Chavez's criticizing USA for this or that reason.

Its true that people of these countries have their hatred for USA but so does the citizens of many other country, but while other countries have moved on and are catering to more important issues, people here are still stuck with USA and reason their leaders. Its time they should move on to and look for other important matters.
