All trade protectionism by heavily armed players who regularly use force is on that spectrum. It would be almost impossible for the US or the UK to engage in protectionist trade practices that are not backed by some kind of military threat.
The idea that protectionism is a major factor in war has long been around;
Frederic Bastiat - "When goods don’t cross borders, soldiers will" (possibly not him, but commonly attributed)
Carl von Clausewitz - "War is a mere continuation of politics by other means"
Henry Kissinger - "if protectionism grows in America or if China comes to be seen as a long-term adversary, a self-fulfilling prophecy may blight the prospects of global order."
Francis Sayre - "The policy of excessive protectionism is like a habit-forming drug. Nations once indulging in it go on from excess to excess; and the appetite increases. But the end of unrestrained indulgence is disaster. Economic nationalism and protectionism spell disaster for the world as well as for the nation...Men will fight before they starve. Uneconomic trade barriers forge the thunderbolts of war."
Sorry for the appeal to authority in using these quotes, but the simple fact is that even if you tried to create a protectionist policy that avoided associations with war wherever possible, the people who implemented it would still see it in military terms as a link between the two has been a fairly common consensus on most sides of the debate for a very long time.
Just to be clear - you do get that I agreed with you in my previous comment? I even went as far as to mildly echo Sayre's comment about economic nationalism.
