This is incorrect. Obama can not affect or control what other countries do. Obama is pursuing a world where the UNITED STATES has no nuclear weapons.
I was born in 1967..at that time... during the JOHNSON administration...the US had over 31,000 nuclear warheads—and over 5000 were HIGH—YIELD bombs—some as high as 25MT!! Now, I realize that with modern targeting and guidance systems we do not need all that many high-yield bombs, BUT we should STILL have a “few” say 50 of them or more of at least 5MT—in case some really “serious crap” occurs—where we need to take out whole cities at once—and not just bases. I am SURE the Russkies still have some SS-18’s out there—loaded with the 25MT or larger”region killer” warhead, after all.... I feel we need something as capable as the Titian II—with it’s 9-10MT warhead, with modern technology,and maybe even a MARV RV,—as a “brute force” weapon—and to SHOW that “if you really mess with us we WILL mess BACK!!
I would say-—we should still maintain around 10K warheads—and their delivery vehicles—with at least 2500 of them over 500KT or so—and 100 or so—over 5MT or so...
