And there's no deal that wouldn't satisfy Democrats as long as a Democratic president made it.
If that's true, why did Schumer come out in opposition of the deal? He's a pretty big piece of the democratic leadership, right?
There's a lot more to this deal than any of us will ever know. And I'd trust our leaders who have access to high level, classified information on what's going on "behind the scenes". Obama's legacy depends really on a few things, but two of them are certainly the ACA and this deal. He literally has his legacy riding on this. If he didn't think this was the best option (amoung many terrible ones), he wouldn't support it.
It's a matter of time before Iran has nukes, if they don't have them already. And the rest of the world was going to move on without us. We would've had even less leverage at that point.
What's even funnier to me about this whole deal is that Iran gained influence in the region after Iraq under Saddam was destabilized. Saddam was a horrible man and leader, but he did provide one helluva counterweight to Iran. Under republican leadership and later proven false pretenses, republicans pushed to oust Saddam. Thus destabilizing Iraq, and allowing Iran to gain influence in the region.
Republicans have in general been very bad at interpreting history in the region, and even worse at predicting outcomes (remember Cheney's infamous "we will be greeted as liberators" BS?). There are simply no good choices in the region, which is what the republicans are essentially rallying for to reject the deal. It's pure fantasy.
Instead, there are nothing but bad choices, worse choices- and horrible choices. It's better to go with the "best" option (like the outcomes presented in many professional examinations like the state bars for attorneys) than to go with nothing at all. Going with nothing at all inevitably leads to on sequences more towards the "horrible" end of the spectrum.
It doesn't surprise me that the republicans are engaging in this type of rhetoric. After all, their platform/litmus tests are full of impossible scenarios- like ending birthright citizenship, deporting every illegal immigrant, banning all abortions (even when forcing a woman to bear birth to her rapist's child would be hell for that woman), etc. I'm not crazy about some of the democratic policies either. It's just that I'd rather live in reality rather than fantasy, and adopt policy accordingly. Doing that leaves you in a much better place.
