Poverty may well be associated with insurgency and the domestic use of terror tactics by insurgents... but that's hardly something that the US or the West need to be concerned with. At the end of the day the solution to insurgency - and thus domestic terrorism - in Nigeria is drastic reforms in the Nigerian government. In the absence of such reform, western attempts to alleviate poverty will only worsen the problem by allowing the government to avoid confronting the need for change.

The US and the west need to worry about terrorism directed at the US and the west, and that doesn't seem reliably connected to poverty. Moot point in any event, as the US and the West can't really do much about poverty in Africa. That's a function of African governance and it needs to be addressed by Africans.
