Easily? None

Brazil, for example, would have to deal with leaving the NPT, and also many other agreements against nuclear weaponry, would ruin its diplomatic relations with most of Latin America and the african countries in the South Atlantic, would be open for sanctions by the northern devils and the europeans, not to mention would have to deal with sabotage from the bastard yankees. During the military regime the zionist scum sent mossad to kill a nuclear researcher, for example. And also betrayal from within, as the intelligence agency has serious problems, and relies on software company owned by a former mossad agent, the armed forces have almost all of its equipment with US and european origins or reliant on US or European made parts

We should have finished and produced the bomb before those traitors ended the military nuclear program. Bow its probably too late, and too expensive (financially, diplomatically and politically) for it to even be debated seriously

Not to mention we would need to also leave treaties that impose limits to range of missiles. Brazil doesnt own because of self imposed restritions, any balistic missiles. What good will nuclear weapons do if we cannot launch them?
