What the role of Black Sea NATO states and clients could be in a multinational, multi-vectored assault on Iran was indicated in the aftermath of last year's Georgian-Russian war.
At a news conference at NATO headquarters in Brussels a year ago, Russian ambassador to NATO Dmitry Rogozin "said that Russian intelligence had obtained information indicating that the Georgian military infrastructure could be used for logistical support of U.S. troops if they launched an attack on Iran." 
Rogozin was further quoted as saying, "What NATO is doing now in Georgia is restoring its ability to monitor its airspace, in other words restoring the whole locator system and an anti-missile defence system which were destroyed by Russian artillery.
"[The restoration of surveillance systems and airbases in Georgia is being] done for logistic support of some air operations either of the Alliance as a whole or of the United States in particular in this region. The swift reconstruction of the airfields and all the systems proves that some air operation is being planned against another country which is located not far from Georgia...." 
Early last October Nikolai Patrushev, Secretary of the Russian Security Council "described the U.S. and NATO policy of increasing their military presence in Eastern Europe as seeking strategic military superiority over Russia.
"The official added that the United States would need allies in the region if the country decided to attack Iran." 
Patrushev stated, "If it decides to carry out missile and bomb attacks against Iran, the US will need loyal allies. And if Georgia is involved in this war, this will pose additional threats to Russia's national security." 
Later last October an Azerbaijani website reported that 100 Iranian Air Force jets were exercising near the nation's border and that "military sources from the United States reported that territories in Azerbaijan and in Georgia may be used for attacking Iran...." 
Writing in The Hindu the same month Indian journalist Atul Aneja wrote of the effects of the Georgian-Russian war of the preceding August and offered this information:
"Russia's military assertion in Georgia and a show of strength in parts of West Asia [Middle East], combined with domestic political and economic preoccupations in Washington, appear to have forestalled the chances of an immediate strike against Iran.
"Following Russia's movement into South Ossetia and Abkhazia, Russian President Dmitry Medvedev acknowledged that Moscow was aware that serious plans to attack Iran had been laid out. 'We know that certain players are planning an attack against Iran. But we oppose any unilateral step and [a] military solution to the nuclear crisis.'
"Russia seized control of two airfields in Georgia from where air strikes against Iran were being planned. The Russian forces also apparently recovered weapons and Israeli spy drones that would have been useful for the surveillance of possible Iranian targets." 
The same newspaper, in quoting Dmitry Rogozin asserting that Russian military intelligence had captured documents proving Washington had launched "active military preparations on Georgia's territory" for air strikes against Iran, added information on Israeli involvement:
"Israel had supplied Georgia with sophisticated Hermes 450 UAV spy drones, multiple rocket launchers and other military equipment that Georgia, as well as modernised Georgia's Soviet-made tanks that were used in the attack against South Ossetia. Israeli instructors had also helped train Georgia troops." 
Rather than viewing the wars of the past decade - against Yugoslavia, Afghanistan and Iraq - and the concomitant expansion of U.S. and NATO military presence inside all three countries and in several others on their peripheries as an unrelated series of events, the trend must be seen for what it is: A consistent and calculated strategy of employing each successive war zone as a launching pad for new aggression.
The Pentagon has major military bases in Kosovo, in Afghanistan and in Iraq that it never intends to abandon. The U.S. and its NATO allies have bases in Bulgaria, Romania, Kyrgyzstan, Tajikistan, Uzbekistan, Kuwait, Bahrain (where the U.S. Navy's 5th Fleet is headquartered) and other nations in the vicinity of the last ten years' wars which can be used for the next ten - or twenty or thirty - years' conflicts.
