No, I&#x27;m against any use of force that <i>isn&#x27;t</i> clearly self defence.<p>(Very Very hypothetically) Russia annexes half of western Europe and starts massing troops on the border and deploying landing craft <i>then</i> you can open fire.<p>It&#x27;s not very realistic purely because of the way the world <i>currently</i> works, as Von Clausewitz said &quot;War is the continuation of diplomacy by other means&quot; and it <i>shouldn&#x27;t</i> be.
