Ukraine affirmed that it may use HIMARS rocket systems to attack Crimea. The spokesperson of the General Directory of Intelligence of the Ukrainian Ministry of Defence declared that Crimea is one of the targets to attack to guarantee the security of the country. But those statements take place after the Ukrainian Minister of Defence Alexei Reznikov said that Kyiv had promised not to use HIMARS systems against the territory of Russia.
The EU was mistaken. The Russian economy was in no way weakened by EU restrictive measures against Russia. The sanctions implemented by the European Union are ineffective vis-à-vis Moscow, but have heavy consequences for member countries.
Sanctions do not help Ukraine, on the other hand, they are bad for the European economy and if it continues like this, they will kill the European economy.
Old and recurrent pro-Kremlin disinformation narrative stating that sanctions would barely hurt or even benefit to Russia while it would dramatically hurt the EU, repurposed to serve in the context of Russia's unjustified and unprovoked invasion of Ukraine.
The EU adopted so far six sanction packages against Russia due to its illegal aggression and occupation of Ukrainian territories. Not all trades restrictions are yet enforced as the energy sector needs longer transition periods so it is too early to assess the full effect of the sanction as that work in a the long term. However, it is incorrect to state that Russian economy would be barely affected or would even benefit from the sanctions. The Russian leadership is constantly demanding the sanctions be removed.
A recent study from Yale University takes a detailed look into the effects sanctions are having on the Russian economy, concluding that "business retreats and sanctions are catastrophically crippling the Russian economy."
