With respect to the ares industries, YC buys into the neocon view strongly enough that it wants to help create the next wave of military tech. The only reason anyone perceives these "threats" and perceives the US to be "woefully unprepared" because of the marketing budget the defense industry has after profiting handsomely from the Iraq wars, etc.
The US is not in danger and does not need new and state of the art weapons systems. We are not losing in Ukraine because we don't have adequate weapons but because we are playing a very stupid and risky strategy. See the comments of Jeffrey Sachs on all of this.
