Um, I'm not sure your description of the US Navy's Sevastopol School project is entirely accurate. Here is a 2014 article at RT.com, which certainly cannot be accused of pro-US bias:

The headline: "US Navy cancels charity projects in Crimea". According to the article, the plan was to renovate School #5 in Sevastopol; the US Navy had already paid for the renovation of School #22 in Sevastopol and School #14 in Simferopol. The RT article states that "Russian media and bloggers suspect the programs were meant to butter up locals for a possible US settlement there." But it doesn't suggest that US troops would be posted there; the only US military "presence" would be a commemorative plaque on the renovated building.
