Do prevailing winds from the West to East also blow from Ukraine across Russia? When it warms up and gets super dry, could incendiary balloon bombs be released in great numbers to drift and set down somewhat randomly and start huge “wildfires”? Might occupy Russia’s attention and resources to hobble their invading forces inside Ukraine.
Dies Russua have crack teams of firefighters to deploy by air to remote wildfire hotspots? Tanker aircraft to scoop up and drop water on them? Or fire retardant? Enough planes and fuel available to do both jobs of firefighting and invading Ukraine? The firebombings of Dresden and Tokyo certainly must have has some morale busting effects upon Germany and Japan. Non nuclear too, for those concerned about escalation to nukes happening. Tear gas would float with the minds too but probably not persistent enough to cause annoyance. Do militaries use non lethal gases in combat anymore?
