Definitely.

However, I think that Hussein had a hand in Samir's death one way or another. He was working with Samir and acted as a messenger between him and the Colombians. By doing so he was in an excellent position to take over Samir's network. I think he simply bided his time. Samir was responsible for some fuckups and because of that may have fallen out of favor of his partners. It could very well have been the Colombians or the Irish gangsters who decided to kill Samir and making new arrangements with Hussein as Samir's replacement for the Dutch market.
