Iran? Nothing to worry about. The last time someone from the ME thought he was 'serious' enough got smacked down toot-sweet. Twice. You know what I am saying? Russia? If anything that is 'serious' about Russia, it is the sorry state of her military's decline: alcoholism, conscription quality and qualification, and systemic corruption throughout the country's political and economic structures. China? May be 'serious' enough in about 20 yrs. What 'serious' combat experience does the PLA has? You know what I am saying? May be it should be YOU who should read what you wrote.
