“I submit that we should do everything possible to stop the war before it gets to that point.”
And what would be your advice on South Korea and Taiwan should their communist neighbors attack them?
Does your argument support or discourage armed invasion and conquest of countries?
Similarly, does supporting Ukraine not discourage the invasion and conquest of countries?
Much more at risk here than many realize.
Thus, we uphold those obligations, preferably by demonstrating strength to discourage any attack.
Supporting Ukraine discourages nothing, especially with Biden having already signaled weakness WRT defending Taiwan.
I don't need any primers WRT "risk".
