During a speech to the Polish parliament, Foreign Minister Radoslaw Sikorski warned that the cost of defending Europe against a possible Russian aggression would reach at least 1.2 trillion euros. This figure underscores the financial burden that European nations may face to ensure their security amid heightened tensions with Russia. Sikorski's estimation represents a significant increase compared to Poland's defense budget, highlighting the scale of investment required for collective defense.

Sikorski indicated that the cost of defending NATO's eastern flank during a Russian assault would amount to at least 1,200 billion euros, a staggering figure that is 24 times greater than Poland's current defense budget. This comparison demonstrates the potential enormity of financial commitment needed to address not only national security concerns but also regional stability. By presenting this information, Sikorski emphasized the urgent need for NATO allies and European countries to rethink and potentially increase their defense expenditures in light of ongoing geopolitical threats from Russia.

The statement follows a broader context of escalating military spending among NATO countries, particularly in response to Russia's activities in Ukraine and surrounding territories. As nations assess their security strategies, Sikorski's comments serve as a crucial reminder of the ongoing pressures and challenges facing Europe regarding collective defense and the importance of maintaining a robust and financially sustainable defense posture against potential adversaries.
