I read in the press that:
"The agreement, negotiated by Turkey and Brazil, it asks that Iran sends 1,2 ton of uranium poorly enriched to Turkey, where it would be stocked, inside of one month. In change, Iran would be entitled of receiving at the most in one year 120 kilos of uranium enriched 20% of Russia and France.
The terms of the pact resemble each other the an agreement proposed by the Occident last year that collapsed for the move back from Iran. But it is not still clear if the USA will agree with him now - partly because Iran continued to enrich uranium, increasing his stock.
The agreement can harm the government's chances Obama of getting the international approval for punitive measures against Iran. China and Russia, that were shown very reluctant in imposing sanctions to a great commercial partner, they could use the announcement to put end to the discussions of additional measures against the country, that they would act turned Wednesday of sanctions."

The only way to avoid new belligerent and criminal episodes (as the invasion of Iraq because of WMDs that it didn't exist) it is to ISOLATE the USA and to remove the legitimacy of his speech of "planetary sheriff". Besides, when doing the empire to REACT to the facts the Brazilian diplomacy impeded him of ACTING freely as it would like.
Point for Itamaraty. Without giving a shot, the Brazilian diplomats removed gunman Uncle San's weapon and they cut his belt. Now he is with the buttocks outside and it has to choose between to catch the weapon or to lift the pants. Any of the two choices will leave the Uncle San badly in the film.
