Eurasian land bridge

I have always found conspiracies to be fascinating and now have developed one on my own. It has to do with the real reason the US invaded Iran and goes back to the old fear of losing the petrodollar. The US navy controls the oceans and can stop any oil going to China by controlling the Straits of Malacca, the Straits of Homuz, the Panama Canal and the Suez Canal. Over the past few years China has built a land bridge from China to Iran. They can transfer oil and other products the whole way in 15 days which is half the time by sea. They signed contracts to buy Iranian oil at a discount price and more importantly to pay for the oil using Juan rather than dollars. China cannot afford to have Iran come under new leadership, especially one friendly with the West. This would put the petrodollar back as the world’s currency and leave China dependent on the West. The rail line passes through Kazakhstan, Uzbekistan and Turkmenistan ending up in eastern Iran. If Iran cannot be stopped by current US plans the next step would be to bomb the rail line.
