Overlooked

My friend and I are writing this story based on a project we did a few weeks ago, and I just want some feedback on how we're going so far!

In this alternate universe, Instead of The Soviet Union backing down during the cold war, they sent nuclear missiles to the United States, killing over 123,200,000 people in the span of a month. The following forty years were filled with misery because the nuclear weapons caused a great nuclear winter, the ash-filled clouds drowning out the sky. After fifty years of the US being uninhabited, people from Asia and Europe immigrated to the pacific side of the US, eventually repopulating the country. They decided they needed a leader, so they chose one. The democracy faded, and rules began to come into place. The government leveled up and took control, deciding things for you, and giving you daily tasks you must complete. Then more people began to have suspicions.
