America is global hegemony and it's rule all over the world what makes for unnecessary wars, regimes and interference policies. In simple words, we can say neo-colonialism.
And it's impossible to corporate with the US government because the US government does not want allies, only vassals and natural resources. US foreign policy exists only to achieve the aim of gathering resources regardless of the cost.
But also, the US pre-emptive policy about Tanzania was wrong. Because they were trying to antagonize the nation that is strategically better placed to deal with the issues in East and Central Africa. Every nation wants to trade, buy and sell, share and create a common market with us. So the US alone cannot slice the pie and control us, never ever.!
Magufuli is an example of African leaders who isn't a western stooge. He is exactly opposite what they claimed him to be. His decision to cancel some of Western firm's lucrative government contracts (including Williamson Diamonds Limited and Symbion) will make our country more comfortable after suffering for many years.
