in sweden war in europe portugals just have to send thier fleet to sweden coast and blocade the hole country. in that case swedens wont be able so sendany troops on the continent what would mean AU overrun al his provs there. +syealand COT is on an island what also mean portugas just have to blocade it, put some nice troops on it and he have it. +it would also mean in a long time sweden could try to send trops to AU true his russian friend. but if he would try that portugals could land in their home land and take the capital and so on. very risk move would that be.
My army have been going to continent walking "near" my russian friend, by my own land ( take a look at map )almost the whole war, few went by the blockable way and few by ships. if u planing to take my capital i can always let there 1k army to defend it

, with ur manpower and ur land morale would be enough (5.850 vs 3.557 max morale according to stats). Now seriusly u cant assault my capital with that morale dissaventage, and winter in sweden is very cold for long sieges, u have no chances to do that.
U cant dow anyways right now cause we have a thruce of last war i won u for 75 ducats or something ( when i was arriving spain by land where i have millitary acces )
In the naval side, according to stats i have 3.150 vs 3.000 max morale, also wining u here. I have a naval leader and my suportable naval is more than 1000 warships (whats ur supportable naval? i bet much less) i can always build them and shrink ur fleet to 0 ships, and end this way the imaginary history of an umbeatable portugal navy.
In the other side RR in austria is higher and higher, and as higher it gets it fewer army can be build. Figthing with mercenaries is no viable, we all can buy mercenaries and when they are wasted only one country can get mercenaries each month (the quicker in buying them).
How u will send 10.000 to austria in 2 years? by loan? not very wise, by diplomats? u would end them soon.
P.S: not say sweden what deal we have to get in our wars, my war against austria is not your bussines, we all know u think game is balanced if u see it naval balanced. we talked about a possible non agresion pact for non embargo pact (portugal alone / sweden alone ), we didn't get deal, u embargoed me when i dowed ottos instead of separate peace what u only signed when u saw u was going to be invaded by land.
BTW i'm not going to sign white peace with austria since he dared to anex my vassal mecklemburg in the current war, they took also 2 provs in another previus agressive war of austria from my allies..
