Maltese will reassuringly find that it reflects America's supportive positive attitude towards their nation. What it does NOT support is overt Russian military influence. Given Russia's occupation of the Crimea, and support of alleged separatists in the Ukraine, any Russian naval or military presence in Malta, even if limited to only the use of harbour and port facilities by warships, would constitute a Red Line for the United States.
The National Security Decision Directive is quite clear on that point. The US would regard it as an "Unfriendly Act and respond accordingly. " An Unfriendly Act " is a conduct (act or omission) of a subject of international law which inflicts a disadvantage, disregard or discourtesy on another subject of international law, without violating any legal norm."
If a desperate Malta, feeling a severe economic downturn as the direct result of the FATF Greylisting, cozies up to Russia for financial support, and is required to allow Russian warships and troops into the country, to include resupplying its fleets, and to allow its sailors liberty on the streets of Valletta, there will be unspecified consequences. Does this mean that the US will continue to oppose a FATF decision to remove it from the Greylist ? And what about the countries of the EU will they implement their own sanctions ?
These are serious issues for Malta to consider, before allowing Valletta shopkeepers to accept Rubles for their wares. Remember, the US can seriously isolate Malta from the global, US Dollar-based financial structure, which would prove disastrous for the country, whose economy is dominated by its offshore sector. We hope that whatever financial benefits Russia has promised Malta, we trust that its beleaguered leadership must realize that the unintended consequences might prove fatal to the Maltese economy. Are you paying attention, Mr. Prime Minister and Mr. Foreign Minister ?
