Brazil enriches uranium to less than 5%, as part of its $1 billion nuclear industry, which will invest on seven new atomic plants to diversify the country’s consumption of oil and hydroelectric power. Brazil plans to start exporting enriched uranium before 2014. Brazilian centrifuges could be used to produce highly enriched uranium. But that’s a matter of political will. The letter of the Brazilian constitution effectively forbids the building of nuclear weapons.
In Iran the situation is actually similar. Both the founder of the Islamic Republic, Ayatollah Ruhollah Khomeini, and current Supreme Leader Ayatollah Ali Khamenei have made it very clear that nuclear weapons are against Islam.
