So I have read until page 2 and here are my suggestions which I often make for Russia in ww1
Do land reform, that is what the people wanted, split the land of the 250,000 larger landowners and give it to the people. Right there lots of political tension will be lost and loyalty of 10s of millions of people will be gained, guaranteeing for one generation election victories. 250,000 will be unhappy, and 10s of million will be happy, easy to win an election.
If done during the war, do so sensibly where one geographic area is done at a time, where you call back the people from that area, distribute the land, then they go back, and then the next area.
Forgive all the debts that the peasants had. This will add to the gratitude and will also add to the electoral victory for one generation of the party that does so.
Install complete democracy, equal rights for all, freedom of religion, universal suffrage etc etc etc
If one continues the war then have it be constant defense and never attack, just pullback. The Russians only need to hold out until at most nov 1918, and there is no way the central power can occupy all of Russia in that time. The Russian government can keep on retreating and pulling back, to the Urals or even Vladivostok if so needed. But it is highly unlikely the central powers will even get to the Urals. Do not do the Kerensky offensive in the summer of 1917, without that offensive, the Russian government may have survived in the original timeline, and in this alternative timeline the chance would increase even more.
Even if the Russian army is pushed back during the whole war, the Russian government only needs to have about half a million soldiers to be able to defeat any faction that might rise up after the war is done, no faction will be able to oppose the Russian government if the government has half a million soldiers or more.
The Russians ordered something like 3,3 million Mosin Nagants to be made in America during the war, only about half a million were delivered before the communist revolution. In this scenario however the Russian government will receive these weapons, 2,8 million extra rifles will be more than enough to defeat any faction, if there even is one.
In the original timeline the whites were not able to hold on to many area, because the whites would promise land reform, the people would side with the whites, and once the whites got in power the talk of land reform faded so the people went to the communists.
In this scenario however land reform has already be promised and started to be delivered so even if somehow there is a communist faction or other factions they wont have enough manpower and definitely not enough fire power.
On the food situation, what the Russian government should do is ask the allies to help repair and increase the Russian transport system, and have the allies ship and deliver equipment and tools that can increase this, instead of delivering weapons that were stuck in warehouses.
If a warehouse is filled with weapons and other military equipment and there is no way to get this equipment out, then instead of getting more military equipment, the allies should send equipment and personal to expand transportation and food.
More cities are to be used to docked at, so that these cities can be given food by the allies and also have their transport capacity expanded, so that nearby villages and other cities also can get food. This will help locally in lowering the food problems where this is done.
China is to asked to help as well. Using allied production and also local Chinese production the Chinese are to help expand as much transport capacity they can in the border area with Russia. China can provide a huge amount of laborers who can do the work, and also food is to be delivered where it is possible to do so.
All of this will help the food situation, it wont fix it everywhere, but it will decrease the food shortages in local areas. For example Vladivostok and should not have any food problems what so ever. Many of the border towns would probably not have it as well, and neither would many coastal cities that are in the East and maybe in North as well. Archangel and Murmansk should be able to be supplied with enough food, and even have their local transport capacity increase so that they can deliver food to nearby towns and villages and perhaps even further.
The money for this is to come from loans for the Americans, but it is the central power who have to cover the loans, so Russia does not need to pay any of the loans, the central powers will need to do that.
On the political side, if any faction that rises up, except the communists. will most likely be nationalistic and against land redistribution, so that means if it even manages to rise up it will have the people against it, making it far easier for the Russian government to defeat that faction.
