On ending the ETTT
We agree that you carrying the alliance's tech must be cumbersome. We are actually surprised that you bore the burden so long without protest. We did not expect you to renew the SAP treaty, as it obligates you to remain a member of the ETTT under section 7.3.*
We have analyzed the ETTT, and in our opinion, Sirius can not unilaterally withdraw honourably from the ETTT. The only way for a member to leave the ETTT is under Section 2.2, which requires consent of all other members, so CDZ, Q and AMAZON would have to vote Sirius out. Of course, we cant vote Sirius out, because Section 7.4 the SAP treaty forbids either of us from voting the other out. So the only way Sirius can get out of the ETTT is to violate the treaty, which means they can be automatically expelled under section 2.3.
Besides comprimising our honour, violating the treaty would almost certainly result in CDZ and Q joining M&M and attacking us both, which we would prefer to avoid. Our espionage production is high enough that we are confident that we would be able to steal any tech that a team outside the ETTT researches as soon as they get it. Indeed, two of the last three techs we contributed to the ETTT were stolen. So we are less concerned with any member leaving the ETTT, as long as M&M are elimminated first.
Of course you already know all of this, but it does not address you issue of not wanting to give any more tech to CDZ and Q. What we suggest, is that Sirius should just stop teching immediately. As you correctly pointed out, we already have the tech advantage we need already to capture the M&M islands, and our espionage prevents them from advancing in tech any further.
If you instead focus on gold, you can bolster yourselves in other areas... upgrades for example, and still stop contributing to the advancement of CDZ and Q. This way you do it without technically violating the treaty and without driving them into the welcome arms of M&M. We are currently preparing to invade Merlot, as you are preparing to invade Mavericks. We also suggest, that you could speed this process along if you were willing to subsidize our upgrades, through a grant or loan while you halt your tech in favor of gold.
Once M&M are elimminated, we could then ask CDZ to vote with us to expel Quatronia as you suggest. Once Quatronia is voted out, the two of us could then vote to expel CDZ. That is the only sane way to do it within the boundaries of the treaty, because if we dump an ETTT ally BEFORE M&M were elimminated, that ally would obviously join M&M immediately, giving M&M all their tech, including Rifling, Steel and Astronomy which would doom the former ETTT allies.
Patience is what we advise our wise Sirian Friends. We look forward to hearing from you.
