The Netherlands and Estonia signed an agreement on Dec. 9/14 for the sale of 44 CV 9035NL Mk-III tracked infantry fighting vehicles. These vehicles are used but were acquired in recent years before the Netherlands decided it no longer needed them, or more accurately, could afford them. The Dutch had announced their intent to sell these vehicles in September 2013, and Estonia had been revealed as their buyer in October 2014.
Russia was already making Estonia nervous after cyber attacks in 2007, but the Baltic states have had even more reason to worry after the events that unfolded in Ukraine through 2014. For Estonia, clearly annexations have consequences.
