The Dutch won all sea-battles against the Spanish and Portugese, who couldn't sail nor fight.
Enquanto os meninos holandeses ainda estavam na escola primária já os espanhóis e os portugueses andavam pelo Mundo.
De resto, basta ver a história militar dos 3 países e chegamos a essa conclusão... nós e os espanhóis andámos a plantar batatas o tempo todo, não foi? 
bem isto foi que me disseram nas mensagens sobre o video:
the Dutch did not loose Brasil. They sold it.
1) It was a private WIC enterprise with hardly any Dutch troops present. Knowing that the Portuguese attacked it during the 2nd Anglo-British war. As Holland was concentrating on England it refused to send any troops to Brasil and let the Portuguese take it.
2) After the 2nd Agnlo-Dutch war the Dutch finished off the Portuguese. They captured Ceylon for keeping (equally profitable as Brasil), sent their fleets, blocked the Brasilian coast, disabling trade, for 2 years, and then prepared for invasion. Portugal being on its knees begged for a treaty. The Dutch agreed in a sale. The Portuguese could keep it for over 60 tons of gold.
They did not loose Brasil, they sold it.
You know little of Dutch history, Woodwater.
The Dutch never focused on Africa except for South Africa. The rest being minor 2nd rate trading posts. There have been no serious Dutch colonisation attempts ever there. Portugal didn't become a serious colonisator in Africa until the 19th centrury when Holland had already totally lost any interest in Africa. The Dutch have always focused on Asia. Africa was to get from A to B, not to conquer from the Portuguese
