How to score victory against government in exile?

TLDR: country without any army/terrain is doing evil stuff with diplomacy, I want them dead or at least to leave me alone.

As unaligned Iran, I started war of conquest against Turkey. Few hundred thousand deaths in war Kingdom of Romania joined the effort... what Romania? They got devoured by red menace early on, few years later Iran, German and Japan forces had big party at Ural ski resorts, conquered twice, no sign of Romania is left, or so I thought. Decisive armored push ends the war, Turkey surrenders. Can't put Romania to grave because they have nothing to give up. Apparently 13 cargo ships and bunch of derelict fighter planes is enough to wage a war against upstart empire...

Once Turkey surrenders, I am left in war against... what? Lets sign peace, nope... I need to be losing to sign peace... Then stupid AI and strict diplomacy strikes in, Romania is too scared to fight alone so they call in my good friend, Commonwealth (leaving them without any oil...). And then I am in war against all Allies because reasons. Tried to google out solution, it gave up and stopped responding, ugh...

Is there a way to end this bloodshed? I have Tibet to conquer ;)

Country in faction won't capitulate, even if it wants to, as long as there are any major countries left standing. In my case Allies are hold together by USA and UK.

Major countries are:

• Germany
• Italy
• Japan
• Soviet Union
• France
• United Kingdom
• United States
• Hungary (in Pact of Rome)

But its nothing that bunch of console commands won't overcome (~ opens console)

Puase game

1. Pause game to avoid side effects
2. tdebug enables tooltip where you can see three letter country tag (here is list because its government in exile has no land to point at)
3. tag ROM to become Romania
4. allowdiplo to allow all diplomatic actions
5. Leave faction in diplomacy with faction leader (UK in my case)
6. tag PER to return to Iran
7. allowdiplo and tdebug again to disable cheats

This caused Romania to surrender right away, which lead to peace conference which composed of half the world passing hundred turns just to get one province because no country left standing scored even one victory point over Romania. Game diplomacy at its finest ;)
