Between 1940 and 1996, the U.S. spent at least $8.75 trillion in present-day terms on nuclear weapons development, including platforms development (aircraft, rockets and facilities), command and control, maintenance, waste management and administrative costs.he United States is one of the five nuclear weapons states permitted to maintain a nuclear arsenal under the Nuclear Non-Proliferation Treaty, of which it was an original drafter and signatory on 1 July 1968 (ratified 5 March 1970).
Although there are several forms of colour blindness, as Aaron Priven noted, the inability to distinguish red from green (red/green colour blindness, natch) is the most common condition. Probably around 5% of men in North America are red/green colour blind (compared to less than 1% of women).
Color blindness is not a form of blindness at all, but a deficiency in the way you see color. With this vision problem, you have difficulty distinguishing certain colors, such as blue and yellow or red and green.he term color blindness is misleading, because most colorblind people see colors, but their color perception is limited and inaccurate. The most common form of color vision deficiency causes inaccurate perception of the colors red and green, making it easy to confuse them.
