What to do to keep Greece neutral?

[Freedom205]

Diplomacy? Any other steps the axis player can take? Every time I invade Yugoslavia (after they flip and join the allies) Greece goes to 90+% allied and then joins the allies the next turn. Capturing Greece then pushes my Barbarossa back until July.

Thanks in advance

Some of the flexibility is in the Axis side. The have a decision event that allows an invasion of Greece by Italy.
If I remember correctly when the Allies support the Yugoslavia coup the Greeks move toward belligerence. I guess the Allies could not support a coup. In that case Yugoslavia joins the Axis.

I wait until Yugoslavia joins the Allies. Then when I attack it, Greece has always stayed neutral.
