U.S. policy towards North Korea has headed down this path for decades. It was the Reagan/Bush administrations that were in charge while North Korea worked on building it's first nuclear plants. Bill Clinton in 1994 negotiated an agreement to have UN inspectors in the country making certain that it's plants were not being used for enriching plutonium for weapons. It was the first such negotiated military agreement between the U.S. and North Korea. As this time line shows, the U.S. never fulfilled completely it's end of the agreement:
After a tense standoff, the two sides reached an agreement. North Korea would allow UN inspectors and cameras into the Yongbyon complex and would cease work on a nuclear plant that could make weapons-grade nuclear material. In return, the U.S. and Japan would provide North Korea with food aid, fuel oil to run its power plants, and would help it build two commercial-grade nuclear power plants, which would generate electricity, but not be capable of producing weapons-grade nuclear material.
North Korea held up its end of the deal, and so did Japan. But the Clinton administration had a tougher time selling this deal to Congress. Congress okayed the fuel oil, but refused to approve the two commercial nuclear plants. Providing any kind of nuclear materials to North Korea was verboten. Indeed, it's possible that Clinton knew he didn't have the votes in Congress to approve the two plants; he may have agreed to that part of the deal simply for expediency's sake. (In other words, he struck a deal that made him look tough and statesman-like while probably knowing that he couldn't deliver on his end and thinking that he could stall long enough to leave the problem to a future president.)
In the meantime, North Korea got tired of waiting for construction to begin on its two promised plants. The fuel oil helped a lot, but they decided to give the Clinton administration a little scare, just to prod Bill Clinton's memory about his unfulfilled promise. In 1999, they fired a prototype long-range missile over the north of Japan, sparking another round of diplomatic talks.
Now, that's not a very flattering portrayal of Clinton's negotiations. He may have promised on something that he didn't expect to be able to deliver and he may have just wanted to stall long enough to leave that problem to the next president. However, that is speculation. What we do know is that the reason Clinton could never deliver on those promises is that the Republican Congress would not let him deliver on it. Even if the speculation about Clinton's motives is true, he was complicit in his actions with the Republican Congress. Further from the article:
By that time the Clinton administration was on its way out, unable to make any firm promises. Clinton managed to extract a promise from North Korea, however, to halt testing of long-range missiles, although no one really believed that North Korea has completely stopped work on its long-range missile program. After all, missiles are one of North Korea's main exports.Clinton became a lame duck and the Republican Congress along with election concerns effectively tied his hands in negotiations. This sort of thing happens with our government and Mr. Bush is about to discover it himself. But let's look at that last line. The article and most media coverage like to immediately jump to September 11, 2001 and the following State of the Union address during which Bush made his infamous "Axis of Evil" remark that infuriated North Korea. However, Bush had already raised the ire of that country:
Then, in 2000, George W. Bush was elected president of the United States. The first thing the Bush administration did was cut off all negotiations and all contact with North Korea.
Bush then elaborated on his concerns. "Part of the problem in dealing with North Korea," he said, "there's not very much transparency. We're not certain as to whether or not they're keeping all terms of all agreements."That quote is from March, 2001. Long before September 11th the Bush administration had cut off negotiations with North Korea and accused it of breaking the 1994 agreement - an agreement that, as noted above, we never fulfilled either. At the time this was one of the first Bush foreign policy steps. The President was widely criticized for this statement. No one in the administration had any sort of proof that North Korea was not fulfilling the agreements. Aides scrambled to cover for the President's words:
So which "agreements" were the president referring to? White House spokesmen told reporters that Bush was speaking about possible future agreements.
