In reality, Russia is not fighting Ukraine, but the NATO. Thousands of mercenaries from NATO countries are fighting along with the Ukrainians, and advanced NATO weaponry such as F16, ATACMS and HIMARS have been given to Ukraine. And despite all this, Ukraine has been losing ground steadily for the last one year or so. And now the Ukrainian military commanders are crying that they are running out of manpower and they need to recruit among the refugees who are currently residing in foreign countries.
The provision of financial and military assistance to Ukraine by various countries to repel an attack by Russia does not at all mean that these countries are fighting together with Ukraine against Russia. European countries pledged to supply Ukraine with one million shells, but never fulfilled their promise. At the same time, during this period, North Korea supplied Russia with about five million artillery shells. And we have been talking about Iranian drones that are launched every day from Russian territory for several years now. But this does not mean at all that Ukraine is also at war with North Korea and Iran.
The Armed Forces of Ukraine have volunteer units from Russia, Belarus, Georgia, European countries and other countries, but there are no regular army units of NATO countries on the territory of Ukraine. On the other hand, Russia itself is actively recruiting volunteers for the war with Ukraine all over the world, as evidenced by the recent outrage of Indian Prime Minister Narendra Modi, who arrived on an official visit to Russia.
