Build surrogate armies? Pay for them, train them, but do not intervene? Jobs are difficult; hiring armies of a 100,000 rifles is peanuts.
Second thing, dismantle the CIA. A look at the recent past shows that most of the horrible situations that the US has got into it have had a CIA theme to them.
The Middle East mess, for instance; Iraq, and then Libya (even Tunisia), and then Syria. All three totally unnecessary, all three having done more harm than good. And that's before saying the 'A' word.
Then the failure to build up a lazy, slack Philippines; they were having a great time, lounging about, entertaining US sailors at their bases, and generally leading the life of Riley, so when the yellow stuff hit the fan, they could do nothing about it except to pretend that they had been against the US, all along, yes, really, Massa, and fall flat in front of a bully-boy China as fast as their spines would bend.
Not being prepared a decade ago, when it became clear that Chinese growth was not an illusion but would continue at a rapid rate; failing to take advance measures and then thrashing about helplessly.
