I do feel bad for Guinea-Bissau. The little country just can’t catch a break. But they do have some interesting ideas, like shooting down drug trafficking aircraft. There is the small issue that narcotraffickers don’t exactly put identifying symbols on their planes (unlike a foreign air force). But that really is the smaller bit of the problem. To quote the BBC:
Earlier this year a consignment of over 2.5 tonnes of cocaine was flown into a military airstrip.
Two soldiers were later arrested in cars which had been packed with over 600kg of cocaine.
Last year around $40m worth of cocaine was found in the capital, Bissau, after a gun battle.
It was stored in the treasury vaults but was never seen again, and nobody has been able to prove the claim that it was burnt.
