ah, makes a bit more sense now.  I thought you were suggesting that other countries should consider them as interims.

although, some of the prev still applies.  granted the sunk costs have been realised and "recovered" but the through life support costs of platforms when they hit 75-80% of their nominal service life starts to make them an expensive procurement child.  The ratio gets ugllier with respect to maint costs and availability and absolute utility.  Thats why larger countries tend to park them or keep them as emergency war stock. (eg the US,  to some extent Canada, Russia and China being good examples of this)
