There had been many sanctions on Russia for invading Ukraine but still, the war still continues. We need to understand that we don't use hard hand to fight hard hands. One will end up being damage and the other can be paralysed or still in a good shape.
The best way to stop this aggression is by negotiation not by sending ammunition to Ukraine for them to fight for themselves. NATO needs to meet with Russia and negotiate on how to stop this war or else, Ukraine will end up being a victim of war. They might lose more cities, friends, if care is not taken.
It is essential that you make it clear that Putin started this war and does not want negotiations other than the surrender of Ukraine, the seizure of Ukrainian territory and the enslavement of its people. On the territory of Russia there are already 66 so-called filtration camps, where hundreds of thousands of civilians from Ukraine are forcibly deported. What kind of negotiations can there be if the Putin regime has already committed the genocide of the Ukrainian people and indiscriminately destroys the elderly, women and children in Ukraine? Russians totally destroy everything in their path: houses, schools, hospitals, plants and factories. They seek to destroy Ukraine's infrastructure and destroy its economy.
An alternative to the current sanctions and the most effective method would be a missile and bomb strike by the international community on all military facilities in Russia and its defense enterprises in order to eliminate the military threat to Russia. Therefore, the current sanctions are still a very humane method for this Russian aggression.
Russia will definitely suffer a military defeat in Ukraine. More than 25,000 Russian invaders have already been killed and about 70,000 wounded. Considering that about 190,000 Russian soldiers have invaded Ukraine, about half of the most combat-ready part of the Russian army has been put out of action. They can announce a general mobilization and draft many million people into the army, but in Russia they already admit that they are not able to equip, equip and feed such an army. In addition, it will most likely not be an army, but "cannon fodder" without military skills. In Ukraine, so far, mainly those who have combat experience are fighting. Therefore, their rebuff is very effective and highly professional. The loss of the Ukrainian military is estimated at 1 to 5 and even 1 to 7 Russian soldiers.
