I can sum it up very plainly in one sentence: government that exists to serve the people, not to serve itself. Hillary Clinton and people of her ilk are parasites upon the American people, selling our freedom to fatten their bank accounts and accumulate power.
More specifically, to me personally it means solving our own problems...
1. Government resources allocated to American citizens, not illegal aliens or migrants
2. Improve/eliminate trade deficit. There's a trade deficit because there's more than a 40% gap in the savings rate of US vs. China. Get people to stop buying so much stuff and you'll have less of a deficit (you'll get a recession as bonus).
3. Revive manufacturing and small businesses. Contradictory, manufacturing is generally big business due to benefits of scale and high capital requirements.
4. Rebuild infrastructure
5. Energy independence/green energy (could be tied in to points 4 & 5)
6. Strong military and improved foreign policy, the threat of force needs to be back on the table. 10 aircraft carriers, 14 ballistic missile submarines, 20 stealth bombers, 139 non-stealth bombers, 1000+ fighter aircraft, 32 Army combat brigades with prepositioned equipment around the globe (i.e. there are more tanks than tank crews), and I could go on. The threat of force isn't on the table? You keep paying for all of that just to have a cool military movie every couple of years?
Plus, the lesson since Vietnam (and ignored in 2003) is that the indigenous crazies are way too committed to give in, even in the face of overwhelming force. You end up with your super military engaged in hopeless struggles (because there are no desirable political outcomes to strive for), which dull its ability to actually engage in the type of conflict its designed for (conflicts vs. nation-states that might actually pose an existential threat.)
The contradiction between Trump's brand of isolationism and a strong military is also curious. The US military is the size that it is because its strategic objective is to be able to fight two large conventional conflicts at once, in different ends of the globe, and win both (i.e. fight in Eastern Europe & Korea at the same time). If you're not going to support your allies anymore, and the new strategic objective were to be "protect the Continental US", you only need a fraction of current force because there are two immense oceans to each side of the country.
7. Racial & ethnic unity through prosperity and excellence (jobs, education, commerce)
8. Reduce national debt, attempt to run the government as a lean & effective business. Many businesses fail to run lean & effective. When someone figures out how to run the government like one, let me know.
9. Restore law and order, let the police and ICE enforce the laws to secure our cities and our borders
