Ridiculous for presenting modern geopolitics as a battle between concepts of liberty. Ridiculous for taking at face value American and Jewish Neocon explanations of their motives "We're for, you know, down with tyranny."
Most ridiculous for not giving the profit motive of parties in power (the defense industry, firms that outsource manufacturing and agriculture, international banks, energy and construction firms, lobbies representing foreign nations) as the motive behind foreign policy.
The United States has never been pro or anti-tyranny or pro or anti-democracy in it's foreign policy. Governments bandy the ideas cherished by their constituents to justify their foreign policy, particularly wars. If the people are devout Muslims, the government justifies its policies on Islam. If the people are mostly secular democrats, you wage every war under the banner of secular democracy. The actual motive is financial, securing or resecuring contracts to the firms that pull the most in the capital (either by occupying the executive and legislative, the various departments with their agents.. or by the lobbies).
