I disagree, I think you're confusing Dinaric/very gracile Euro features with MENA features. South-Western Europeans, such as the Southern French; North Italians & Spaniards do exhibit a wide range of phenotypes that are local to their respective region. The most notable one is the Baskid phenotype that's prevalent across South West Europe:
Honestly, South-Western Europeans look extremely similar to their North-Western European kinsmen.
Apart from some exceptions, they are mainly distinguishable from Northern Celtic/Germanic Western Europe. The ignorant assumption is that they all look like Eastern Meds in Southern Europe. However, even in Northern parts of Spain and Italy, you will find Eastern Med looking individuals. Just look at football players from Asturias, Galicia etc. and it will be noticeable that many look clearly different than North-Western Europeans. David Villa for instance. Even some of the Basques have a swarthy look to them. Not surprising considering how Haplogroup E-M81 is found in relatively high numbers in areas as far North as Galicia and the Pasiegos Valley of Asturias. This is not necessarily due to the Arab/Berber invasion of Iberia. These territories were not held by the Muslims for long, not at all in the case of Asturias. One also has to bear in mind that before the Roman Conquest of Iberia, there was ethnic diversity. For instance, Phoenicians established colonies in Iberia.
As for the Portuguese, they have a long History of miscegenation. For example, they did not necessarily exile their Sephardic Jews but assimilated a lot of them because they contributed to the coffers of the King. A community of Crypto-Jews survived into the 20th century in Tras Os Montes. The Portuguese also encouraged miscegenation in their colonies and would in many cases acknowledge offspring from such unions unlike the more conservative Caste system of the Spaniards. Cristiano Ronaldo is an example of this as one of his female ancestors was Cape Verdean. Don't also be fooled by his tanned looks, he sunbathes etc. a lot and was much paler in his formative years at Man Utd before he became a celebrity figure.
Nonetheless, Northern Portuguese are no different than Galicians. There is a language continuum between Portuguese and Galician as one would logically expect considering that Portugal is an extension of Galicia due to the Reconquista. A 'Celtic/Germanic' phenotype that Spaniards stereotypically associate with Galicians is also applied to Northern Portuguese. Hence, why there are stereotypes that paint Northern Portuguese as being more representative of a Historical Portuguese/Galician population than a 'Swarthy' Alentejan etc.
As for Northern Italy, their 'Germanic' status in exaggerated. The Lombards and their Barbarian allies were few in number in contrast to the pre-existing Romanised population. Furthermore, some of the German tribes they assimilated into the Lombard confederacy were not exactly pristine Teutons. The Germanic Gepids, for instance, had Eastern influences.
As for the present, there has been so much internal migration and intermarriage in both Italy and Spain that the differences between the regions are becoming blurred as exemplified by the massive migration of people from all over these countries to major industrial centres such as Bilbao, Milan, Turin, Madrid, Roma and Barcelona.
Germany are Arsenal, it’s people always bang on about reachieving greatness when the reality is that they were never great.
Germany is a 19th century creation. After the formation of a Klein (Small) German State by the Prussians and the Iron Chancellor, they were without doubt the strongest power in Europe. Moreover, this is excluding the German led Austrian Empire. Most Eastern Europeans spoke German as a second language in urban areas, such was their dominance of Continental Central and Eastern Europe. The Germans do not get a lot of global attention because they did not focus on colonising the 'darker' world. They were busy colonising Cadaans in Eastern Europe, just like their ancestors colonised the remnants of the Roman Empire and created modern Western Europe.
In regards to Alsace, it is not Moselle, Lorraine (Metz) is in the Moselle Valley. Alsatians are ethnic Germans who ended up joining the French Kingdom because of a 17th century treaty between the dominant powers of the time which stipulated that Alsace should come under the sovereignty of the French King. They were overwhelmingly Alemannic German speaking until the Post-Napoleon period when France sought to create a unifying national identity that revolved around the use of the French Language. Corsicans (Italians), Dutch speakers in Dunkirk and the surrounding region, Celtic Bretons in Brittany, Catalans in Rousillon, Basques in Bayonne, Franco-Provencal speakers and the numerically significant Occitan speakers in Southern France were linguistically/ethncially marginalised as a result of this drive to manufacture a French National identity. French was only spoken in the traditionally Frankish/French elite heartland of North-Central France.
