Agreed very strongly.
> Infiltration of foreign companies in allied or neutral nations purely for economic or geopolitical insight, not for military purposes (Brazil's Petrobras oil company, all sorts of spying in Germany and Norway and other places).
See this is where the NSA really shines. We (The US) delayed Iran's nuclear program by THREE YEARS with Stuxnet! Three! And after they finally figured out it was sabotage the US and Israel had the director assassinated for further delays.
Having Merkle's cell phone? During the Eurozone crisis? It would have been awful (financially) for the United States not to have that information. It's fun to look back and read the confused reports during the time "European Union suffering considerably from Eurozone crisis; America sees only limited effects."
PETROBRAS? We won offshore oil drilling locations because we had that information. Energy security for the country going forward decades.
Unfortunately geopolitics are important and you can't just not participate. Hacking is (one important way) that modern espionage, surveillance and sabotage are done.
