It has already been reported that several Russian attack drones entered Polish airspace on Wednesday night, and those that posed a direct threat were shot down. It was the first time that Russian drones were shot down over NATO territory.

"Putin believes he can get away with this provocation because he is bombing Ukraine with hundreds of missiles and drones, and this is likely due to Trump's recent actions. Trump recently stated that he is"not happy with the whole situation" in Ukraine.

"But Trump has not confirmed his repeated warnings and deadlines, so Putin may think he can always count on another two weeks," the newspaper said.

After the Russian dictator met with the leaders of China and North Korea in Beijing, Russia deliberately attacked EU diplomatic institutions and other Western assets in Kiev.

Then Putin decided to launch 800 drones and missiles into Ukraine, killing civilians, including a mother and an infant.

"Meanwhile, the Trump administration appears to be cutting US security funding to the Baltic states, NATO members that understand the threat posed by Putin and demonstrate it with their high defense spending," the WSJ reminds.

The newspaper added that the Trump administration may be pressuring Europe to impose more sanctions on countries that buy Russian oil, but the US itself has not yet imposed restrictions on China for purchasing the same product.

"Trump still hasn't signed the Senate's bipartisan bill on such "secondary" sanctions, despite having the support of more than 80 senators. This soft stance could be a semi-quixotic attempt to make a big deal with Beijing, but the president could forget about it if he lets Putin fool him on the Ukraine issue," the WSJ notes.

The drones' arrival in Poland shows that appeasing Putin poses risks that go beyond"embarrassing the United States." The Russian dictator is showing that his imperial project is not limited to Ukraine, the newspaper says.

"A direct confrontation between NATO and Russia would be a disaster for the world, which no one wants, but the weak US response increases the likelihood of war. The fact that Putin believes he can send drones to Poland, a US treaty ally that hosts about 10,000 American troops, is a direct threat to US security,"  adds WSJ.

The newspaper concludes that Trump knows exactly how to put pressure on Putin: more sanctions, more weapons for Ukraine and fewer restrictions on their use, as well as strengthening NATO's military power so that Russia cannot surprise the alliance unprepared.
