1) They don't just want to go to the moon, they want a permanent manned base. Like Mir or ISS, except not in orbit around Earth but on the moon. It's the next logical step.
2) They planned it for a long time now, but due to economic pressure/sanctions they're weathering the storm and putting it off for better times. Does anyone seriously doubt that oil prices will go up in the next year or 2? Is anyone seriously that naive? High oil prices is just icing on the cake, spending/beer money. They have enough to live on without it.
3) There isn't much financial investment in either Syria or Ukraine. Ukraine will fall apart nicely on its own, they just defaulted on debts (I was born there.....I follow the situation and have family/friends there, it's only a matter of time). Humanitarian convoys to Donbass don't cost that much, neither does supplying the region with ammunition from time to time. Crimea only needed a bridge and a power cable run to them, it's a matter of a few billion and a year or two that's about it. They literally have 1 base under 1,000 personnel in Syria, like 30-60 planes. It's not exactly budget breaking. Unlike Iraqi Freedom bs it won't take a decade, again a year or so. Syrian army does all of the ground work.
So if you notice a lot of these things come down to a year or 2...... Sounds like good time to wait a little for them.
