Is it really so different though? The outcome of both situations is the same. Migrants are dying, through direct action and deliberate inaction.
Mediterranean nations have the opportunity to protect lives, but instead they choose kill / let migrants die.
When a government is informed that people are dying within its waters, and the gov has the capability to respond but deliberately chooses not to because the victims are “african”, you think that the government bears no responsibity for their deaths?
