Iraq, Afghanistan and now Libya! Where will US stop?

Through your esteemed column I would like to say that one more Islamic country, Libya, has been a victim of the wrong policies of the ruler Qadhafi! The US struck 112 Tomahawks missiles at Libya, which cost 7.28 billion rupees approximately.
Apparently it feels that the US is sympathetic to the Libyans but actually she is not! The US-fired missiles were just an investment in Libya and surely she will receive its cost back occupying the oil reserves of Libya, which is surely her main purpose! This is the only wealth of oil because of which the US has always interfered in Muslim countries, especially the Middle Eastern countries by hook or by crook! In fact, all the oil business is being run by powerful US companies!
I have some questions that as the US and her allies claim that they are the champions of democracy and human rights, where have they been sleeping for 42 years when a person like Qadhafi took hold of the government? Why didn't they think about Libya at that time?
It is in the history of the US and her western allies that they have always supported those Muslim rulers, who in fact, could control their people because if the Muslim world get-democratic freedom, it can create an undesirable situation for the US and her allies, as they have their strategic goals like the oil reserves etc. This is the basic reason that the US and her western allies have set dictators in the Muslim world so that they can save western interests in their own countries and in return, can freely rule over the people for 40 years or more and pave the way for monarchy! These are the only so-called champions of human rights, who leave the Muslim dictators when they see that they are losing the hold over their people and then, they immediately remember the rights of the Muslims' and seek a "reason" to crush their own "Pitthu".
Unfortunately, no Muslim ruler has ever learned a lesson from this state of affairs though it has always happened! That is why, we observe that a queue of Muslim countries appear to be victim of conspiracies by the US and her western allies and the latest addition is Libya! O Allah! Have mercy upon the Muslims and show the righteous path to our rulers! Amen!
