We have been in a "cyber" cold war with the Chinese (and others) for years. The recent theft of IP at RSA and many other companies is due to reasonably sophisticated persistent malware (advanced persistent threat in marketing terms) that can take a medium size business months to eradicate with outside professional help. Basically, there is a lot of information gathering going on and a lot of theft of things the US tries to restrict the Chinese from acquiring. To underestimate their abilities, goals, and motivation is foolish. To think we are being any nicer to them is absurd.
