Re: As an intellectual and technological excercise...
While it's absolutely true that much funding has come from military, it's logical to assume if we didn't spend money on the military, we'd spend it on something else, or conversely, because the military was funding it you didn't need to fund it elsewhere.
However, look look at your specific points;
RADAR Christian Hulsmeyer first used radio waves to detect ships (collision avoidance) - Not military
Spread spectrum radio - the link between this and CDMA (etc.) is tenuous at best, it is similar technology but with decades between them it's hard to credit this development with what is used today.
GPS - pretty much a military funded invention, pretty sure it wouldn't have happened (at least as soon) without this funding (I'll give you that one) doesn't mean it wouldn't have been invented of course.
The Integrated Circuit - not sure why you think this is a military invention, Werner Jacobi first suggested (and patented) this idea (simple amplifier) and proposed it's use in hearing aids, the first people to use IC's was the USAF, but it's hard to call it a military invention per se.
The Internet - merely a network of networks, often attributed to the military because of it's "redundancy during attack, ARPANET" this is untrue and a popular myth, notwithstanding, even if this was the case I think it's pretty obvious that universities were going to connect their networks regardless of the military aspect (and proposals for networks such as Merit preceded it, X25 etc.)
Nuclear power - This is an odd one, primarily because the first looks into nuclear power were non military, then the use was militarised (for weapons), and only after WW2 was nuclear power used for (usable) engery creation, there is an argument that the use in war stunted development for power as the government regulated and controlled it's use (with explicit classification).
