They aren't going to take the risk. Trump might as if he thought his move would make him a hero. a strong man in some eyes. He wouldn't care about repercussions. He wouldn't care. And that is not an argument for Putin wouldn't have done it if Trump was the president.
Why shouldn't it happen Faug.....Any confrontation with Russia is WWIII....
WWIII could happen anyway. A brief synopsis of WWII causes are frighteningly parallel to those existing with Russia today.
Take for instance Japan (and note some of the parallels) Why Imperial Japan Went to War With America Over Oil
“It has been truly unavoidable and far from Our wishes that Our Empire has been brought to cross swords with America and Britain… They have obstructed by every means Our peaceful commerce and finally resorted to a direct severance of economic relations, menacing gravely the existence of Our Empire. Patiently have We waited and long have We endured, in the hope that Our government might retrieve the situation in peace. But Our adversaries, showing not the least spirit of conciliation, have unduly delayed a settlement; and in the meantime they have intensified the economic and political pressure to compel thereby Our Empire to submission.” Why exactly did Japan elect to attack a country with twice the population, five times the steel production and seventeen times the gross national income? The answer all came down to a U.S. embargo on imposed in response to Japan’s brutal invasion of China. https://nationalinterest.org/blog/reboot/why-imperial-japan-went-war-america-over-oil-171254
And then there is Germany, with several consequences of the Treaty of Versailles
What were some of the consequences of the Treaty of Versailles?
What were some of the consequences of the Treaty of Versailles? The treaty forced Germany to surrender colonies in Africa, Asia and the Pacific; cede territory to other nations like France and Poland; reduce the size of its military; pay war reparations to the Allied countries; and accept guilt for the war.
What were the consequences for Germany stated in the treaty? The treaty was lengthy, and ultimately did not satisfy any nation. The Versailles Treaty forced Germany to give up territory to Belgium, Czechoslovakia and Poland, return Alsace and Lorraine to France and cede all of its overseas colonies in China, Pacific and Africa to the Allied nations. https://colors-newyork.com/what-were-some-of-the-consequences-of-the-treaty-of-versailles/
Germany suffered economic hardship, as well as cessation of land (much like the breakup of the Soviet Union) that allowed Hitler to rise to power.
The parallels of embargoes of oil and trade, along with economic hardships that ensued, pushed both Japan and Germany to war. So, sanctions and embargoes are not always safe strategies to thwart adversaries. It is a gamble either way, that could also cause a world war. The ais of Russia, China and Iran could be a formidable one, each of which have some of the same grievances.
