Have you realized that there are not really any checks and balances on what takes place to make sure that no president is making a mistake or exceeding authority to go nuclear.

Article II, Section 2 of the Constitution states that “The President shall be Commander in Chief of the Army and Navy of the United States” and both courts and legal scholars have long interpreted this clause as giving the President direct command over military operations, including decisions about when and how to use specific weapons.

Indeed, no statute or constitutional provision requires the President to get approval from anyone else before ordering a nuclear strike.
Many legal scholars would agree that a President must seek congressional authorization before ordering a first use of nuclear weapons in any non-emergency scenario.

Nevertheless, in practice, every President retains the physical ability to order a first strike without asking Congress first as the launch system does not distinguish between retaliatory and first-use orders. The button to push is located on an electronic “nuclear football” that is carried around in close proximity to wherever the president is at by a military aide.

it is past time for Congress to act to disable the “nuclear football” in any situation where the United States is not itself actually and demonstrably under attack. The thought that Donald Trump might be considering pulling the nuclear trigger to make Israel happy is just too frightening to bear but Americans must be aware of that possibility!
