After the 2nd week, not by
I think can probably get NJ to 25% and the Helios in this week.
I could have a manticore earlier, I had the resources but just didn’t build it because of the way it goes up with Synedrion, so I wait to get the Helios 
The focus on Synedrion has also hold me back for NJ, otherwise I would have done one sabotage for NJ to get them also on 25%.
(Edit: I thought about it earlier on, look at the report from 15.01., NJ was on 9%, one sabotage and I would have them on 24%, exactly the value to get them supportive but I was greedy to get Syn aligned ASAP and the sabotage would decrease their reputation)
Anyway, it is still very random and here again I got lucky with my starting position but somehow unlucky with the second mist. The two not defended and destroyed Syn havens “cost” -6 rep …
I also run in problems in my first campaigns until I realised that it is not a good idea to recruit so many soldiers when the vehicles are much cheaper (compared 3 soldiers to 1 vehicle) but very effective in the early game. The same with bases, you need maybe one or two additional bases in the first weeks but not much more. It is simply way to expensive.
