Who's at war with who

[Sabre21]

Here is an interesting question for those of you that have been playing the boardgame for a long time or have been a beta tester.

The scenario is that the Germans and Italians are both at war with Greece and France. Only Germany is at War with the CW. Greece is aligned with the CW with both German and Italian troops inside Greece. There are CW ships in the Eastern Med.

1. If Italian ships move into the Eastern Med will they engage or be engaged by the Brits?
2. If CW troops land in Greece and stack with a Greek unit can Italian land units engage the stack?
3. If Italian ships are in the Eastern Med, may they or the Brits add naval support to the battle if it is a coastal hex?
4. If there are no CW troops in Greece and the Italians are attacking a Greek land unit in a coastal hex, may the Brits provide defensive naval fire support being that they are aligned with them?

From what I understand the answers should be 1. no, 2. no, 3. no for the Italians and yes for the CW, and 4. I'm not sure. I just want to make sure I have somewhat of a clear picture of what should be able to take place once the lead starts flying.

1. No
2. Yes (since the hex is Greek controlled)
3. Both (since the hex is Greek controlled and CW units are under attack)
4. No (but I'm not totally convinced about this. It's my first impression, since no CW troops are in the attacked hex).

I agree the answer to #4 is no, and for the same reason.

[Extraneous]

A caveat to #3.

3. If Italian ships are in the Eastern Med, may they or the Brits add naval support to the battle if it is a coastal hex?

Option 38: Surprised naval units can’t provide defensive shore bombardment nor can naval units provide defensive shore bombardment to a hex containing only surprised units.

3. Both (since the hex is Greek controlled and CW units are under attack)

I agree.

There is an example in RAC that I think helps with the answer to question 4 so I cut it in below.

Cut from 9.9 Multiple states of war:
....
Example 3: The USSR is launching a land attack against German controlled Finnish units in Helsinki, before
Germany and the USSR are at war. The Germans could fly Finnish aircraft in support, but could not fly German
aircraft nor provide German shore bombardment unless a German land unit was also in Helsinki.
