Polish Foreign Minister @sikorskiradek just schooled Czech Deputy Prime Minister @petr_macinka into accepting that the European Union operates as a democracy. Populists have nowhere to hide when met with hard facts. An extraordinary exchange. Well worth a watch.

Považuji za důležité připomenout nasazení a oběti, které státy Aliance přinesly během konfliktu v Afghánistánu. Česká republika byla součástí misí pod vedením NATO a naši vojáci, kterých se tam vystřídalo přes 11 tisíc, neúnavně plnili úkoly v náročných podmínkách po celých 19 let. Na afghánském území zahynulo 14 českých vojáků a desítky dalších byly zraněny. Jsem pevně přesvědčen o hodnotě kolektivní obrany a respektu mezi partnery, kteří sdílejí závazky vyplývající z článku 5 Severoatlantické smlouvy.

The VS Code ecosystem is unreal. • You can write Python in VS Code • You can write Java in VS Code • You can write Shell scripts in VS Code • You can build Dockerfiles in VS Code • You can write Terraform in VS Code • You can manage Git from VS Code • You can edit YAML files in VS Code
