If any foreign weapon enters Ethiopia, outside of the oversight of the government, the only supply chain route is the rouge regime in Eritrea. This means also the Ethiopian government is duty bound to eliminate all the risks, including the supply route of dangerous military hardware to the internal rouge elements in the country, to protect the safety of its citizens and ensure the sovereignty and territorial integrity of the nation.
This has to be achieved by removing the rouge regime in Eritrea by means of force and protect the security of the nation, for once and all.
Patience has a limit!
