Basically nothing, which is why "open source" is diametrically opposed to export control. IF technology is going to be allowed to transfer to Russia AT ALL, which I don't support, there should at least be a significant charge in dollars for it.

EXPORT CONTROL??? We're a Capitalist society, You must have the US confused with the Old Soviet Union. What you're proposing is the same central control that Marxism used.

What then is to prevent the Russians (who DO NOT have nuclear missles pointed at us BTW), or anyone else from reverse engineering proprietary software as the Chinese who Microsoft is dealing with presetly, have done? The next proprietary agreement that the Chinese keep will be the first. YET, Microsoft continues to deal with them, KNOWING that proprietary agreements have not been historically kept by the Chinese.

Nothing but the law, which may not stop them, just like the law doesn't stop shoplifting. But you don't reward shoplifters with free products, you tighten your controls, and prosecute where possible. Conversely, open source = no control, i.e. no law.

The next proprietary agreement that the Chinese keep will be the first.

So your answer is GIVE it all to them, for FREE instead? Sorry, I don't normally use all caps, but since you do maybe you'll get the point.
