It's just accusations that the priates are claiming in the name of piracy.
Also this quote I find hard to believe in:
Highly unlikely. More likely, we'll continue to buy AK-47's and possible nuclear weapon.
Again, Somalia needs to advocate for itself and form their own government instead of being a "pity me" type of mentality.
I would be surprised if they didn't buy weapons, yeah. Not sure about nuclear weapons But you asked for a link on dumping waste, and got it. As we can see, it's loads of info on waste dumping in Somalia by searching google. Perhaps you want to read the reports from UN on this(again, just google).
Some pirates talking bullshit does not mean a "pity me" mentality throughout Somalia, but I see your point, and one can speculate what the pirates tried to do when making those claims. Somali warlords recently threw out the US aided ethiopian invasion, so some of them must have some guts left.
