I would like to add that even after the War Powers Act was passed, the United States had fought in two wars and stage at least 9 military interventions. So, yeah, this law is completely ineffective if it was supposed to limit the president's power.

While this is true, I want to add that in addition to being the president of the United States, he has his own special set of powers that come with the job. One such power is to use military force without the consent of the Senate. When creating the executive branch, the Framers intended for the president to be, "able to respond quickly to external, foreign threats" (135) along with the president being Commander in Chief of the US army and navy. With this in mind, the president can use his power to send troops to other countries without the Senate's approval. If he does it right, the president could pass an executive order that can provide the military with enough funds to carry out its duties.

Even though Congress has the power to make laws, it is ultimately up to the president to decide what exactly becomes law. He signs the bills he likes and kills the others by vetoing them.

The executive is more powerful because the president is able to expand his powers in times of emergencies completely side-stepping Congress if needed. For example, if the United States are invaded, the president can immediately declare war on the attacking country with no input from Congress at all.
