Protectionism is different from hawkishness. If he were hawkish he'd be calling for heightened US carrier presence in the South China Sea and calling Taiwan independent. He just wants to keep manufacturing jobs in the US - I doubt he'd sound any different if those jobs were going to Kenya or Turkey or Ireland or any other country. And it's not like it isn't a policy without it's own problems - ask any third world Maoist about labor aristocracy and they'll tell you - but just because it sometimes lines up with hawkishness doesn't make it the same thing.

Bernie's foreign policy is absolute trash and Parenti was right to break with him over Bernie's support for the destruction of Yugoslavia.

If Bernie managed to get elected and not get couped in the process, then by some miracle he managed to implement the domestic reforms that he envisioned, it would be social democracy at home and some variation of business as usual on the international level.

Still, I think that Bernie would rely upon popular support and that means that imo he'd be more responsive to his voterbase than "Let's vote him in now and push him left after" Biden would be. But who knows?
