Concerns have emerged regarding the potential withdrawal of 10,000 U.S. troops from Eastern Europe, which could embolden Russian expansionism and weaken NATO's deterrent posture.

In light of the ongoing conflict in Ukraine and potential threats from Russia, European countries, especially those on NATO's eastern flank, are increasingly recognizing the need to bolster their own military capabilities.

Ukraine's military leaders have issued stark warnings that Russian forces could occupy the Baltic states within a week, emphasizing the need for immediate and effective responses from NATO allies.

Former Lithuanian Foreign Minister Gabrielius Landsbergis has underscored the urgency for these nations to prepare for possible aggression, drawing parallels to Ukraine's situation.

Analysts have pointed out the critical necessity for enhanced ground-based air defense and strike capabilities in Europe, as current resources are severely lacking to counter Russian threats.

To address these challenges, Landsbergis advocates for the implementation of a 'Sky Shield' in Ukraine's airspace, which would involve an international air force comprising up to 120 European aircraft.

The European Sky Shield Initiative aims to improve air defense among NATO allies, although participation has been slow from some countries, including Poland.

The article also highlights the importance of nuclear sharing within NATO, noting that the significant reduction of the U.S. nuclear arsenal in Europe could undermine NATO's credibility as a deterrent against Russian aggression.

Since 2017, permanent NATO battalions have been stationed in the Baltic states, with ongoing commitments from countries like Germany and the UK to maintain and enhance their military presence in the region.
