Not sure about the girls being a false flag but Boko Harem did get juiced from that bullshyt that went down in N. Mali due to the Islamists who got the guns and heavy weapons after Ghadaffi's ouster. I still boil about what the Europeans unleashed on Africa by that dumb move but it is what it is now.
There are a couple of real suspect things beyond inventing conspiracies with the anti-Boko Haram war in Nigeria:
1. As stated before, Nigeria squashed Boko in 2009. Where the hell did they get all the money and guns?
2. While Nigeria is fighting one of the world's worst Islamic insurgencies, the West has them under an arms import embargo to the point Nigeria is trying to develop their own domestic weapon's industry (good thinking). Why the hell would they do that now?
I initially believed the girls were kidnapped at first. However, after examining the things that happened after that:
1). Western countries sent their special forces and spy planes to Nigeria. Then left after about a month, only for them to come back and start building military bases in neighbouring countries.
2). The alleged girls were released in batches but as soon as they were released, they were all shipped to the US.
3). There was an arms embargo on Nigeria from the West, especially the US after that, I had to question a lot of things.
A lot of things just didn't make sense based on how big the news was and the things that happened subsequently looked funny. It's basically like the so-called Arab spring. When it was happening, we all thought it was real and spontaneous. However, today, we know it was orchestrated by the CIA, via the social media and the sleeper cells they have in those countries. And they were targeting certain countries: Libya, Sudan, Yemen, and Syria. Only Sudan managed to escape the onslaught.
