The smaller nations I can understand, and the history of Germany and their wariness to be a world military power again I can understand, but the sheer lack of any force projection by any European nation is crazy. Aside from the UK and France, no European country can operate their military in any effective manner outside their borders and even then, the UK and France had issues achieveing air superiority over Libya, troubles with refuelling etc.
Europe has always thumbed their nose at the US over the fact that they have universal healthcare and free tuition, but they have always been subsidized militarily by the US. Granted it is a mutually beneficial agreement, but 2% of GDP for military is still historically low amounts and countries like Italy and Germany definitely need to start spending that. Estonia and Poland contribute their share because they know how valuable NATO is to their defense against a possible resurgent Russia.
I definitely think Germany needs to get their head in the game and up their military spending. As the EU largest economy, they need to be a military power as well, especially in an era where Russia is annexing territories, China is stealing land near reefs and corals, NK developing nuclear weapons.
