Anything could be used as a weapon of war because all warring nations want to win by all means. Russia wants to pressurize the West to do its bidding because it seems that sanctions have started hitting the Russian economy hard. The economy that was portrayed as sanctioned poof is gradually losing its strength. The war is costing so much and it was not expected to last for this long. This halt in this grain deal will affect the world, especially poor nations.
But Russia also raised some valid points. The Kremlin claimed that the West is not keeping its part of the agreement. Russian agricultural products have been restricted from the international market, which is against the agreement. Another point is that one of the main reasons for this agreement is the negative effect the grain blockade had on poor nations. Russia agreed to lift the blockade because many poor nations might experience severe food shortages. But from different reports, it is only 4.5% of grains from Ukraine went to poorest nations. Most of them were diverted to influential nations.
Russia said it is willing to come back to the negotiation table. And as citizens of one of these developing nation I expect that this issue will be settled because the last time the gains supplies from Ukraine was halted, most of us couldn't afford bread. But the perfect solution to all these problems is a peaceful resolution of the war in Ukraine.
A bit of clarification.
Yes, bravado and populism are over in Russia. It turned out that in 2-3 weeks nothing has worked out, Russia is mired in a difficult war, the army is a fake, the economy is a colossus on "feet of clay"..... That is why the west is systematically and monotonously crushing and destroying russia's economy.
The fact is that after Russia loses the war, which is already obvious, there is no guarantee that Russia will be divided into several independent, adequate states. And if Russia manages to preserve its integrity (I hope it will not), it will restore its economy, military-industrial complex, and, having learned from experience, will repeat what it has been doing since 2014. And the world doesn't need that. Therefore, the degradation of the economy should be at such a level that attempts to restore the economy of Russia will take 20-30-50 years.... And this is an acceptable time to build an international system of containment of such inadequate regimes.
Regarding "violations of agreements". There are none. The way out was announced after the defeat of the military infrastructure object "Crimean Bridge", on the territory of Ukraine temporarily occupied by Russia. After which Russia made demands:
- to lift some sanctions that do not allow to receive Western technologies (Russia is technologically left country, like it or not, it is a fact)
- Connect Rosselkhozbank, owned and controlled by Patrushev's son, to SWIFT. This bank used to participate in international aid programs, and more precisely, under the guise of this, made operations on "laundering" and withdrawal of funds of the Kremlin's top brass.
So there are no violations of the agreements, read Russia's statements.
