1, Irrelevant complaint. It is not up to the President of the United States to stand up to "political correctness", it's a grassroots public issue, and it is up to the public to decide what is PC and what is not, through public discourse.
2, The deportation of the US migrant population would be EXORBITANTLY costly, and would damage the economy and effectively collapse law enforcement. The problem with immigration comes from the demand for cheap migrant labor.
3, How will he pay for another war? Iraq and Afghanistan cost about 4 trillion USD up to this point. What's next Syria? Iraq 3.0? Iran? How much will that cost? 4, 6, 8 trillion? And how many lives? 10000? 20000? 100000? When will enough be enough?
4, Lowering taxes? How? Dismantling the structures of the government? Cutting military spending? How? Your 3rd and 4th points are mutually exclusive. Quite on the contrary, he would either need to borrow HEAVILY (some more from China?) or raise taxes. The trade deals with China benefit US companies, and consumers (not labor tho). Companies manufacture cheaply, consumers buy cheaply. Furthermore you can't unilaterally cancel trade deals. It is doubtful the President has the authority to do so, plus it would cause massive damage to the US economy.
And why would you want the US to be feared? When did the US become Nazi Germany or some third world dictatorship? The US and what it represents should be admired, not feared. The world already fears the US. Worldwide everyone polled considers the US a greater threat to world peace than they consider ISIS. They already think the US is half run by warmongering lunatics with access to WMDs.
