The cost of expansion is prohibitive  The costs of NATO expansion are prohibitive at a time when the Western European members are scaling back their defence budgets and the reducing the size of their conventional forces. The Clinton administration estimated the costs of the initial expansion to be $27 to $35 to 2010, but this is mostly the costs restructuring and of making forces interoperable rather than the costs of protecting the new members. [1] The cost of stationing forces in Eastern Europe would be considerably higher and if NATO ever had to defend these countries the cost would be higher still. Given the fragile economies of the new republics, the existing NATO States will be obliged to absorb the expense of expansion. Even a decade after expansion the new members have mostly not succeeded in reaching the 2% of GDP the alliance targets and their combined defence budgets are only a third of Russia’s. [2] The proper question is whether the taxpayers of the US and Western European States wish to pay to protect citizens of distant republics from phantom threats.
