The presidency is one branch of three in the US federal govt, each with supreme power in their particular roles. The primarily powers of the presidency relates to foreign policy, as opposed to the congress which writes the laws and controls the budget. So an example of a power regarding who controls military capabilities doesn't prove the president is supremely powerful in a discussion about writing laws. Unless you imagine the president will use the military domestically like Caesar to create a dictatorship (which people keep predicting for pretty much every single president, yet hasn't happened).
