The first scene that really popped out at me was seeing the Doctor and UNIT watching Osgood read a prepared statement that the rebel Zygons are forcing her to read. It looked just like other hostage videos that ISIS makes their hostages read while being videotaped. Pretty easy one to see, but it doesn't end there.
One of the major discussions in these episodes is the discussion of Zygons fitting in with humans here on Earth. The same arguement is being made here in the U.S. and all over the world about accepting Syrian refugees. Are they coming in to do us harm, like what possibly happened in Paris, or are they people without a home and fleeing war? I think one could argue that the Zygons are like these fleeing Syrian refugees. The Doctor even remarks that people would be worried that the Zygons will take all their benefits. I've seen the same comments about Syrian refugees coming to the United States. People here are wondering why are we helping these refuges instead of helping our own. The last similarity that stuck out to me was when the Doctor said that if we bomb them, then the peaceful Zygons will become radicalized like the rebels. That's what's been happening in real life. Bombing Muslim extremists in a lot of cases just creates sympathy for them and radicalizes more Muslims to their side.

Overall, I give "The Zygon Invasion" & "The Zygon Inversion" a 3.5 Tardis's out of 5. These Dr Who episodes, as unintentional as they were, really spoke to me about the problems our world faces today. I urge everyone to go back and watch these two episodes and think about what we are facing today in our world.
PS. The Doctor wears underpants with questions marks on them. I think I know what I want for Christmas.
