Foreign involvement in Africa is far from unique to Russia (Leaked documents reveal Russia’s efforts to exert influence in Africa, 12 June). The new scramble for Africa involves more powers than the first round over a century ago. This time it’s in part about securing resources such as oil, gas and rare earth metals crucial for military and civilian digital technology, and denying these resources to rival powers.

The United States Africa Command (Africom) now has 7,500 American troops active in all but one African country, up from 6,000 in 2017. Apart from its huge base in Djibouti, controlling the narrow strait between the Red Sea and the Gulf of Aden, a vital chokepoint through which all shipping using the Suez Canal has to pass – most importantly (for the Americans) Chinese shipping – the US has constructed small “lily pad” bases, whose presence gives the US a strong military capability.
