Get the country together and have all the scientists and mechanics work on drilling machines and suits, while the rest of us get a start on digging. Conact China, Britain, Australia, and others and tell them to do the same. Once one of the drilling machines and suits are made, one person would drill their way down to the center of the earth, preferably a bomb squad member. With every suit and machine made, somebody else would go down and we would have thousands just in America drilling to the center of the Earth. At the center, we would meet up with the other countries and work together to diffuse the bomb, and we would successfully diffuse it 5 seconds before it goes off, and all are happy. The tunnel created by the digging would then become a cheap way to get from America to Europe or Asia.
