This whole situation is extremely suspicious. This guy has a fascination with Islamism and is a convert. Much like Pvt Bargdahl. I suspect this guy was trying to join the taliban. Let's be honest. No rational person would take their 7 month pregnant wife "hiking" in Afghanistan. 

Some questions worth answering. 
How did they even get into the country? 
What was their purpose there? 
Has a background check been conducted on these two? All evidence points to them having been radicalized. 

Thankfully these two won't be getting a 10million dollar check.
