Iran says "Avoid South Korea" and "No war with South Korea"

Whether it is considered a troop deployment or a dispatch is a matter of how Iran perceives it, not South Korea.
The US also fires missiles at Iran and sinks its vessels,
but they never call it a war.
What would happen if Iran attacked a tanker heading to South Korea in retaliation?
What should we do if a patrol aircraft is shot down or there are casualties?
Femco will start a GR (General Reaction/Rant), and South Korea will have no choice but to deploy more troops.
Approval ratings will probably go up.
It would be like Lee Jae-myung becoming Netanyahu.
