Interesting point about Malta. Neutrality is enshrined in their 1987 Constitution with one vital caveat:
"Malta is a neutral state actively pursuing peace, security and social progress among all nations by adhering to a policy of non-alignment and refusing to participate in any military alliance.
Such a status will, in particular, imply that:
(a) no foreign military base will be permitted on Maltese territory;
(b) no military facilities in Malta will be allowed to be used by any foreign forces except at the request of the Government of Malta, and only in the following cases:
(i) in the exercise of the inherent right of self-defence in the event of any armed violation of the area over which the Republic of Malta has sovereignty,
or in pursuance of measures or actions decided by the Security Council of the United Nations; "
Wonder if that last point will be mentioned by the world and his dog asking for basing facilities at Luqa?
