Is the US on the Wrong Track Regarding Its Policies?

Is the United States on the wrong track regarding its domestic and foreign policies?

Terrorism, a virus pandemic, unrest in the Middle East, conflicts in Iraq, Afghanistan, and Syria, weather catastrophes, energy dependence, global warming, health care issues, unemployment, racism, the immigration crisis, school shootings, gun violence, government leadership, election tampering, impeachment of the United States president. These issues are just a sampling of the many concerns currently facing and dividing the American people. Is there room for optimism in a society so overwhelmed with problems, or are there so many things to be discouraged about that instead of optimism, all one can see is the rise of pessimism and feelings of hopelessness and powerlessness?
