Only if you accepted the premise of debating protectionism on purely economic grounds, which would be foolish. Economics as a whole should never be argued on purely economic grounds, because that would make it useless.
That is one of the benefits of it, not the only benefit. Or, more accurately, it is one of the weaknesses of "free-trade," which I am criticizing.
I accept no such thing, only that "free-trade" has observable and significant detriments whilst only having theoretical benefits. I don't have to conclude that "free-trade" is economically beneficial in order to say that it erodes national sovereignty. That makes no sense.
You either erode national sovereignty or you don't. "Free-trade" erodes national sovereignty — that is unquestionable — and there doesn't need to be anything said besides that. To extend it further as you are doing is to go past any criticisms of "free-trade" and into a different area entirely.
Trade does the opposite of ensuring peace, especially "free-trade."
International agreements erode national sovereignty and are not war-proof. Moreover, you're a fool if you believe any international agreement is "war-proof." This also has made the tacit assumption that war is bad, or that peace is the end goal, which it isn't. My criticism was that "free-trade" is an irrational policy to survive conflict, not that it is an irrational strategy to prevent conflict. A desire to be able to win wars is not the same as a desire for never fighting them.
No, globalism is cancer. How is "create an international police force" the solution to "stop the erosion of national sovereignty"?
That's just a precursor to forming a larger country of the constituent parties, which is really just a way of saying "acquire more resources." It's a legitimate strategy, but irrelevant to the discussion.
Britain's allies weren't due to trade, for a start, and "not dying" hardly counts as "winning." The US and USSR won the war; Britain survived it.
It's a cost with no benefit. Dependency doesn't cause alliance; it's more likely to do the opposite. Interdependency included.
Yeah, that's the thing, that isn't an option with "free-trade." "Free-trade" — as you pointed out — causes interdependencies, to the point that if the Mexican currency had collapsed it would have taken the dollar with it. That's the situation that allowed Mexico's extortion. An independent US would have been able to seek the goods it wasn't reliant on elsewhere, but "free-trade" prevented such an ability. Similar things are going on right now with US currency reserves held by foreign nations, and because of "free-trade" we can't afford to say "no."
That sounds pretty protectionist, mate.
I have yet to look into the full arguments, but a preliminary one I would make is that if you cannot freely trade the resource of labor (according to economic theory) then it isn't truly free-trade. That's a definitional argument, and another I would make is that in order to realize the full (supposed) benefits of free-trade, labor and other resources must be allowed to freely flow so that they can wind up where they are most efficiently utilized.
Yes, it did. Unemployment grew substantially after 2008, but it was already thriving and healthy beforehand.
And what's your point? "Free-trade" has almost certainly caused unemployment, loss of wealth, etc., etc. in previous times (without busts or booms, I might add), rendering your statement irrelevant.
