Only once in this game have I ever been attacked by a russian, all the others i've met have been incredibly helpful and friendly, albeit once they have established where i'm from.
But, i'm sure you get the point by now.
If you have the materials and want to stay, then as borka says, your first priority is to close off that gate, either by building a new one onto it or just building in front of it, if it's the latter you can always rectify it once you have your ram.
If the worst comes to the worst and you have to leave, look at it as a chance to find a better spot. With no baggage or ties you are free to roam and find yourself some useful nodes. I always make a wilderness alt to travel around and it paid off well this world, so well that i'm in the process of moving my main from her original base even though she is quite established where she is - there is always a better spot somewhere.
Good luck!
