We're not trying to make the Communists lose, here. Regardless of if they win or lose, helping them at all will lower our standing in the eyes of anyone who hates communists, including Britain (since you seem to care about that), Germany, and the US. They do hate communism, by the way.
Early on in Soviet Russia's history (between 1919 and 1929, I think), Britain invaded Russia with a bunch of other countries to "nip Communism in the bud" as it were. The invasion failed and the Soviets hated the West even more.
There was no invasion, merely minor "help" for Whites from Western countries in Civil War, and not even because of communists, it was because they retracted from the war, and they didin't like Germany not fighting on both fronts.
Fuck that anyway, just send guns to everyone.
What? No, I think there's some confusion. We give the pistol to the British and we give something else (maybe the F14A) to the Chinese. We give the pistol to the British to insult them. We give the F14A (or another weapon) to the Chinese. The way I see it, the Royal Army is looking for a weapon that'll be cheap no matter what, even if they only have the minimum amount of resources. It's why I don't think we should submit our grenade.
They want a machinegun, not rifle or grenades. The commies would possibly want a grenade, but you don't want to help commies.
Making the British like us may be the strategic thing to do but fuck it! This is what the British get for forcing Arstotzkans to work in their plantations like common slaves! We are Arstotzkans and we have our pride! We can improve our relations with the British but not if it means apologising for throwing off our shackles of slavery and oppression!
Yadadadadadada, they didin't even managed to stay long enough to make us work at plantations. Give them something good, and do it quick.
Both Moskurg and Arstotzka sent their spies to steal some intel from their sunken submarine in order to get Design credits. They were both captured and in the year after, rebels started appearing in both Arstotzka and Moskurg. After some espionage actions, the US were found to be directly tied to both rebellions.
Glory to Arstotzka.
Stealing from Americans =/= helping a country on the other side of world, that they don't even care about, yet. It won't instantly cause them to drop everything and pop destroyers by our shores.
