| Liquid-fueled missiles, of a class with the Atlas, Jupiter, and Thor IRBMs, and Titan ICBMs developed in the early to mid-1950s, were cumbersome, expensive, and volatile. |
| The military authorities, however, regarded Polaris as but one part of a nuclear triad including ICBMs and bombers, each with its own function. |
| I don't think Canada has a major role as a northern neighbour, but it does have a political role as helping to defend the entire North American continent, not only from ICBMs but from bombers, from close-in weapons. |
| I felt that by the time our efforts could bear fruit there would be a major threat from Soviet ICBMs armed with nuclear warheads, and I made this point to my colleagues. |
| So the reason that nobody emphasizes the biological agents carried by ICBMs is because they don't have any solution to the problem. |
| Not only does the treaty require the parties to exchange this semi-annual data, but it also requires special notifications on the movement of non-deployed ICBMs, SLBMs and heavy bombers. |
