Nicolás Maduro and Ukraine
With the invasion of Venezuela to capture President Nicolás Maduro, the USA has nicely undercut its 'sovereign territory' objection to the Russian invasion of Ukraine. I am sure that President Trump, President Zelenskyy of the Ukraine, and President Putin of Russian Federation are acutely aware of this.
Each will have their own reasons and motives for drawing parallels and of saying that the analogy has limits and what applies to one does or does not apply to the other. But whichever way it is described, it seems to me that President Trump has handed President Putin an argument that sways the balance away from the support of Ukraine.
