International stability?
With Saudi Arabia now distrusting USA and deciding that it will go it's own route to possibly getting its own nuclear weapon?
With Israel now saying it was a terrible deal and that it will attack if Iran gets to a nuclear bomb?
The whole point of that sanction was to STOP ENRICHMENT ALTOGETHER. Not just slow it down.
It is not even doing that. You act as if Iran and USA reached agreement. They have not. Iran believes the agreement allows them to do certaing things that the USA claims they should halt. So there is not even an agreement on the agreement.
The Saudis have always distrusted the USA since 1990 when they first let them install bases on their soil based on lies
The sanctions were not about getting them to stop enrichment altogether. that was the lie fed to people like you. the USA knows full well that Iran has the right to nuclear power. Heck, they were the primary proponents for a nuclear Iran back when their boy Reza Pahlahvi was in power.
The sanctions were about destabilizing Iran, and reducing it's power in the region.
Israel wants to to remain the big dog on the block, and Saudis want the Sunnis to remain the ruling class in the Muslim world.
A wealthy prosperous, thriving Shiite nation is not in the best interests of either Israel or Saudi Arabia,
...however Israel & Saudi Arabia are not the only countries on the planet, and not the only nations and economies affected by Iranian sanctions.
What you and so many people like you fail to recognize is that Iran does NOT have nuclear weapons, is NOT making nuclear weapons, is a signatory to nuclear non-proliferation treaties, and has subjected itself to international oversight, ...something Israel, which DOES have nuclear weapons has failed to do.
Think man think, ...and discover your own talking points, ...not just what the media pundits tell you.
