The western countries were fine with a weak Russia. However, as soon as a revival of the Russian economy started and the country announced its status as a global power, it was accused of human rights violations, interference in domestic affairs of the US, Ukraine, and other foreign countries, cyberattacks, etc. The saying "Carthage must be destroyed" has been converted into "Russia must be destroyed" which has become an integral part of US politics and ideology.
It is a very sad conclusion, but Washington strongly marginalises Poland. Despite the feeling that Poland is a strategic partner for the United States, today, it is becoming a junior partner on the absolute margin of the US foreign policy.
A common pro-Kremlin narrative promoting the idea that Poland is a country without any real international importance or political significance. Poland is often presented as an American “puppet-state”, which does not represent any importance for the USA.
The US authorities have repeatedly stated that they perceive Poland as its ally in Central Europe and one of the strongest US Continental partners. The US and Poland implement such strategically important projects as the increase of the US military presence in NATO’s Eastern Flank, modernisation of the Polish Army, diversification of Polish gas supplies, etc.
In 2019, Poland was added to the US’s visa-free regime and in the summer of 2020, a new defence agreement with Poland was signed. Deals have also been signed on the purchase of LNG by Poland from the US.
