Is Russia Really Unfazed by Trump's Comments?

Introduction
Recently, US President Donald Trump made a bold statement, calling Russia a 'paper tiger' in their fight against an aimless war. However, the response from Russia has been surprisingly restrained, according to the BBC's Steve Rosenberg. This raises the question - is Russia truly unfazed by Trump's comments, or is there more to the story?
Russia's Military Strength
Despite Trump's claims, Russia's military power cannot be underestimated. The country has the second-largest military in the world, with advanced weapons and technology. In recent years, Russia has shown its strength in conflicts such as Syria and Ukraine. It's clear that Russia is far from being a 'paper tiger' and has proven its ability to engage in strategic and focused warfare.
Political Calculations
Russia's response to Trump's comments may also be a calculated political move. The country has been under pressure from the international community due to its actions in Ukraine and alleged interference in the US elections. By downplaying Trump's words, Russia may be trying to avoid further tension and scrutiny. It's a strategic move to maintain a level of diplomatic relations with the US and other world powers.
