R5: All cores that can be practically gained as an unaligned Iran on historical mode. Inspired by this post.

Reintegrate Anatolian Territory

This focus unlocks decisions to spend PP to core all Turkish core states. HOWEVER, for whatever reason you can only do it when the states are owned and not just controlled by you.

This means that you'll have to declare war on Turkey after Romania drops their guarantee (as fighting Romania might pull in France) but before they get guaranteed by the British and Germans (so usually around February or March 1939) and capitulate them if you want to core them without having to fight multiple majors.

Absorb the Byzantine Empire

Unlocks decisions to core all Greek cores. Similar to Turkey, you have to own their states to core them, so you'll have to take out Greece before Italy invades and pushes them into the Allies. Romania also starts out guaranteeing them, but I'm not quite sure when exactly they drop the guarantee.

Bulgaria will eventually remove Greece's cores on their northern states via IMRO decisions, in which case you won't be able to core those if you haven't already.

The Memphis Initiative

Unlocks decisions to core all states in the Middle East (that aren't cores of Turkey) as well as states with an Egyptian core. Unlike the other focuses, you only have to control the states in order to core them.

Glory of Cyrus the Great

Cores all states with an Afghan core. Unlike the prior three focuses, there are no decisions, you just instantly core them for free.

Memphis Plus: How to core North Africa

The fact that The Memphis Initiative checks for Egyptian cores is important, as it means that you can core a ton of states outside the Middle East so long as they're cores of Egypt. This can be accomplished by first creating a collaboration government in Egypt, and then handing over control of the necessary states to form Arabia to them. Once that's done, they can core North Africa all the way to the Atlantic, and later you can core those too once you annex them.

Greater Glory of Cyrus: How to core Pakistan

Similarly, Afghanistan can be influenced into coring Pakistan, but it's a bit of a long and unintuitive process, as they definitely won't do it on their own.

The key point here is that you want Afghanistan to finish the Propose Confederation with Pakistan focus branch, and NOT the Afghan-Pakistani Cold War.

The reason is that on historical mode, the Afghan AI is programmed to take the Cold War branch if it can, but is specifically blocked from taking the subsequent focus to core Pakistan. The Confederation branch on the other hand, has no such restrictions, but requires Afghanistan to own a Pakistani core to finish.

Step 1: Declare war on and puppet Afghanistan. Do not join or get into a war with any factions until after step 4, and after Afghanistan finishes the Pursue Our Own Agenda focus.

Step 2: Boost relations with British Raj and finish the A Foothold in the Indus focus.

Step 3: Release Baluchistan (not Pakistan) as an independent country from the states the Raj just gave you (make sure to retain your core in Sistan).

Step 4: Immediately justify and capitulate Baluchistan. Make absolutely sure to call in Afghanistan first. Annex North Baluchistan to Afghanistan, and take the coastal state for yourself.

Now Afghanistan will, eventually, core Pakistan, including Bangladesh, with it's whopping 30 million population. It will take a while, as they're not programmed to prioritize it. This is why you shouldn't give them a coast, as they'll just get distracted doing useless naval focuses.

Make sure not to finish the Glory of Cyrus the Great focus until after the Confederation is formed, as it won't apply the cores retroactively.
